PagePlus Cellular Deceptive, immorrale and illegal practices Holland Ohio

Purchased the $ 80.00 plan for 1 year of service for my 89 year old mother--- a safety plan. Four months later, the phone would not call out or allow calls in, and a message asked for a refill. My mother only uses this phone a few minutes a  week.   Page plus states that I still have a balance with them of 30 some dollars. It turns out they misapplied my correct purchase of the year-long plan as a pay-as-you-go monthly plan. Which, she does not need, nor did I buy. In speaking to a supervisor, they would not correct their mistake. I have the documentation as to what I purchased. This is theft. Already registered a complaint with BBB. Have contacted the Attorney General's office in Ohio.  Will start a small claims proceeding soon
