Incorrect billing and poor customer service

Ive been a multi choice customer for over 15 years,and I'm extremely frustrated with the poor customer service I've received.im experiencing consistent billing errors ,which have led to my subscription being suspended and the representative sdont know how to address these issues , I've lost access to my service and I'm being billed incorrectly,it's aggravating to wake every few days to find my subscription suspended while a paid my account,then have to call in repeatedly.only to deal with staff who can't effectively resolve the problem. Instead of solving the problem they cancelled my subscription without my concern.
