Not refunded as promised

I contacted edgars with regards to all of the fees that I was being charged for, these were 3 service plans that I had not agrees to pay and didnt even know about. I called them and even went into edgars thrice to sort out this matter, eventually I was contacted and promised I would be refunded by July. It is now September and I have not been refunded and I am still being charged with content mobile fee, service charges and a protection plan that I have never agreesd to. When I called in they said I need to contact their agnecy thats dwaling with this. But I dont understand why I need to go around wasting airtime and wasting my time phoning different companies to sort out their mess. I was promised that all of those charged would be credited back to me in the month of July but when I call in its always a different story. So why should I stick to their agreements and pay them when they cant even deliver on their on side. This is ridiculous and I definitely will be taking this further because I had enough of running around wasting my petrol, time, airtime and effort trying to get help from someone at Edgars. They are ripping people off and getting away with it!
