Skills, not prompts.
Tell the caller to stop and to name their company. Put that same request in writing. Log every later call. Register a personal cell at DoNotCall.gov. That registry does not cover a business line. Then use the lookup and the skill below to check who is calling the shop.
The letter template, with the number or email you looked up filled in, and the directory name when the lookup has one. Change anything still in brackets. You review it and send it yourself.
Other letter types. The finance skill is the next step if you want a call log.
Which broker shop was a work number or work email reported with? Broker rep lookup. One identifier. Not a directory.
Tell the caller to stop and to name their company, then put that request in writing and log every later call. The lookup and the skill on this page are the next step.
Tell them to stop calling and to name their company. Then end the call and put the same request in writing.
No. The FTC says the National Do Not Call Registry covers personal phone numbers, not business numbers. Register your personal cell there, and use the company-specific do-not-call request in the stop letter for the shop line.
Log the company name and the pitch, not only the number. A new number from the same shop still goes on the same log.

Without a key the lookup allows 10 lookups an hour and 30 a day per connection. A key raises that to 100 a day. It is tied to your email for abuse handling only.
The right letter depends on who is calling. Calls after a stop request can be TCPA violations that can come with real payouts. General information, not legal advice. You fill each letter in, review it and send it yourself. Served from /v1/templates.
For: MCA / business-lending broker, lead-generation / marketing, direct lender, vendor, business caller.
A company-specific do-not-call list request that covers every channel and revokes any consent they claim. Asks for written confirmation and a copy of their do-not-call policy.
For: debt collector.
A written request under 15 USC 1692c(c) that the collector stop contacting you. It says it does not dispute or admit the debt. An optional validation request under 15 USC 1692g asks the collector to verify the debt first.
Information only: Regulation F presumes a collector is calling too often at more than 7 calls in 7 days about a debt. The FDCPA covers third-party collectors and may not cover an original creditor or an MCA funder collecting its own debt.
For: any caller that contacts you again after your stop request.
Logs the later contacts as facts, repeats the request and asks for written confirmation.
General information, not legal advice. MCAFax is not a law firm. No dollar figures and no promised outcomes: whether you have a claim depends on the facts.
These follow-ups are not answered in the sections above.
MCAFax may receive compensation from some providers. It does not affect our grades or what we show you. No signup. Without a key you get 10 lookups an hour and 30 a day; a key raises that to 100 a day. Only the one number or email you enter is sent to MCAFax.
Business owners who use MCAFax log the calls, texts and emails they get. The lookup shows what those logs say in aggregate: the kind of caller, the number of merchants who reported it and the first and last report dates. It is a possible match in MCAFax's records, not proof of who called, and every entry stays unverified until MCAFax checks it.
Ask for a correction or removal from a lookup result. The entry is hidden while we review it. We acknowledge within 2 business days and decide within 5, and log the outcome without your details.
Calls after a stop request can be TCPA violations that can come with real payouts. Whether a call breaks the rules depends on the call and the line; the protections for a business line are narrower than for a personal one. General information, not legal advice. MCAFax is not a law firm. Talk to a lawyer about your own calls.
No. It logs what you type after a call: the date and time, the number or email, the name and company the caller gave, and the pitch line. There is no call recording or transcription.
