Since I filed for a DBA a few years back, I've been getting calls every day on the phone number that I included on the DBA form. These aren't telemarketers or robocallers, but other businesses trying to sell me business-related stuff (pens, mugs, stationary, business credit cards, etc).
The number is listed with the do-not-call registry, but I'm thinking that since I listed the number on the DBA form, the do-not-call list might not cover these types of calls.
Is there anything I can do to make the calls stop? I haven't turned up any good suggestions in my searches for this particular situation.
