does not leave message and when i call back...dead air space,

Same thing call with no message... call back dead air

Calls no one answers, Then a few minutes later a collection company with an 800 #, from the same area in Ohio calls back wanting someone who used to have my number.( I've had my number for 2 years and can not help if it's the only one they have on file for her!) They say they will remove the number, and starts all over again on Monday morning 9 AM. They will NOT stop calling even if you never heard of the person they are looking for.
