Bad customer service

I called in to cancel a contract that was due for an upgrade..I wrote a first review, 2 months later I am still getting money that's deducted from my account after speaking to many consultants.. Last month I thought maybe it was a mistake but it went off again. Although the amount has reduced but having money that I don't know it's for what being deducted from my account is frustrating especially in the times we are living in..
