Fingers Crossed for you, but in general crooks don't take requests. Ignore and block the calls. Answering, calling back and talking to them at all, even to say "NO" will get you more and more calls.
After receiving 40 calls from various numbers in a week and answering a couple already -- each time it was a recorded message from Gwen wanting to know if I wanted to talk to someone about Medicare Supplement and I answered no. This time I decided to ask to speak to someone for information -- a very nice lady came on the line and I told her we did not need information but I needed our number taken out of the system -- and I am happy to say I did not receive any calls today. Thought I would share just in case you are getting tons of these calls -- might be worth a chance.
