Monthly MTN subscription on Edgars account

from 2013 I noticed this MTN subscription on Edgars account and I went to the store to have this cancelled and my account be refunded. The following month I will see a principal debt adjustment and the very same adjustments is put through again and the following month. for crying out loud I'm on contract and I am so done with this company. They are really ******. They told me they will investigate the matter and get back to me as to who is the airtime getting loaded to. until today still no response. every time I call in they are offline or will have to wait for over 30min to get to speak to an agent.
