Terrible, horrible service

I am being harassed by MBD consultants, every single day (from 7am till 18pm) My account is up to date. They harass my husband too, irrespective of asking them not to call everyday. They dial and hang up, one does not even know if the call is legit or not. But 24/7 is really irritating. Please stop increasing your fees by calling a person every hour or even when their accounts are up to date.
