Received the same ROBO call, credit card machine is non-compliant, called my merchant service provider as the only terminal they recommend is the one I have. Upon further investigation found that Advanced Merchant Services, Inc. is tied to Wells Fargo Bank and Advanced Merchant Services (AMS) is associated with HSBC. Either these institutions don't care about customer service or are getting enough payback from the service provider to ignore the dishonest tactics being used by this group, as they all use the same LOGO.
I let the call go to voicemail and they left a robo message about my credit card security being out of compliance and it being urgent that I call them back and update it immediately! Sounded like a complete scam to me, because it was NOT my bank calling.
I also received a voice recording on Maisel number urging me to call another number to take care of some terminal for a credit card without giving me the name of the card.
I immediately called the original number back and after three attempts somebody answered and says that I have a business and my credit card on file with the business needs to have the terminal updated or some bogus crap. I told her to take my name off the list!
Got a robo-call, stating their records indicated my credit card machine was out of compliance and that it was urgent that I contact them immediately., I called back and got a person. I told her that I'd gotten their call and was concerned for whomever they were trying to contact because they must have dialed a wrong number since they called a personal number and I don't have a business, much less a credit card machine. They asked for my phone number and I told them it wouldn't be of any use since they dialed a wrong number. I wished them luck in finding whomever they were trying to contact.
