OnAir robbing their clients

OnAir is treating me badly as a customer, they are not taking my calls, they are not returning my calls, they ignore my emails and refuses to assist me, reason being that I have reported them to Hello Peter before. A lady by the name Jamie contacted me afterwards claiming that Onair Agent Musa Inkomo did misled me by selling me the Dstv stream package, and they will cancel and collect the product at no fee. They made sure they debited the package from my account and still did not collect the product. She begged me to remove my review from Hello Peter and give her good marks. I lve send them an email and an Agent by the name Denver Smalls is refusing to help me,

How can I get this issue solved without taking them to court? Please help!
