Collection agency, calling about  T mobile. Wants to collect termination fee, etc.

I get a call on my cell from this number everyday. When I answer no one is on the phone except a machine. I do not talk to machines and would prefer them not to call me either. Sometimes I wait long enough to press buttons saying that I am the person they/it is looking for or that I am not, even though I can not understand who they are asking for, but either way the phone hangs up. During their message they do leave a number to call back but I don't get it cause they say it so fast.

this is not the sharon e. robinson and it's ok tht u called just please stop cause i get about 20 calls a day for people asking for here so thank u and have a blessed day
