Transtech Merchant Group Caller tried to verify my business information stating something about my check, cash, credit and debit acceptance fees Carrollton, Texas

I got a call today about my cash, check, debit and credit transaction fees, stating I might have been overcharged, I tried to explain that I did not conduct any business with them, and asked if this was a sales call. I was told no it was not, then I was asked to verify my street address and that I was still in business, I told them it was none of there business and they rudely hung up on me, the phone # that showed up on my caller ID was bogus. If they have to hide the number they are calling from, I would never do business with them, and on top of that , I do not accept debit and credit cards and I tried to tell them that, now if someone shows up at my door, I will have them picked up for soliciting without a license and criminal trespass, because I did not authorize anyone to come to my business, which is not open to the public anyways!
