Repais and Incorrect billing

Put through my Tablet to be fixed through Edgars insurance in August even now when I call I am told they awaiting full description and I had given it three times already,today i called again and spoke to an agent by the name of Lerato who put me on hold for 25 minutes and then hanged the phone,the consultant who was assisting me from campus square by the name of Bob was so helpful that he rang them again and this time he too was put on hold until i left the store after been there for an hour.Another thing is that Edgars has put me on some Mobile something for airtime and have not signed up for that,I am been billed on that I called the department for cancelling there on the 29 Septenber Millicent said I will be called back even now I am still waiting I had to pay for something I didn't take I used to love Edgars but right now I want nothing to do with it, i will not encourage anyone to have an account there it is so ridiculous that I am thinking of closing my account that I have had ever since I started working years ago.Edgars doesnt care it is only ripping its customers of
