Phone numbers get transposed all the time. YOU are not being singled out. YOU are not being watched.
If the call was not meant for you, get your number removed from their call list. It is simple to do. Don't feel like you are being made to go out of your way to be removed. One way or another, your number was entered in their system. That makes it YOUR responsibility to have it removed.
So called NEW phone numbers are just ones being reused. It was someone elses number before it was assigned to your phone.
Got a message from toys are us Geoffrey giraffe wishing me a happy birthday. It's not my birthday and have never shopped at Toys Are Us. Do not call list is a waste of time.
