Money debited for airtime I am not receiving

For over 2 years now that I have subscribed to the airtime special offer that was made available to me. Sadly, not once have I received the airtime irrespective of countless times I have raised this query with Edgars. I have been promised to get call from supervisors that never came through. At some instances, my calls have been cut after been made to hold for eternity. All I request now is for all the money deducted from my account to be paid back. I intend to cancel this airtime nonsense and the funeral policy I have with Edgars because if I can experience so much PAIN regarding this airtime thing, how much more if I was to put through a funeral policy claim. I have lost all manners of respect. In my experience, professional ethics do not exist in Edgars.
