Just got a new phone and phone number.  I received a call from a company that the person I spoke with insists that I called them using a different number the background noise sounds like a call center.  This is the only phone I have and the only number I have.  In the past few days I've gotten similar calls but the incoming phone number is different and they also insist they called me using a different number and they don't find a record of my number in their system.    Again, the background noise is so bad that I can hardly make out the company name. This is strange and getting annoying!
