Consistant Pathetic service from JET

I have been to the branch more than 5 times they call headoffice and log a ticket then i keep having to send my proof so can someone please tell me who the hell knows what they are doing??? I do everything you guys ask of me..even pay on time.. yet no one can fix my account..it costs me money to go to the store and airtime to call head office all the time.. this has been on going since november last year. Can someone take responsibility and fix my account already! Or refund my 300rand! I keep writing on hello peter and someone calls then process starts by me explaining myslf den dey send me to the store all for the store to call them again and submit my proof of payment..like does edcon even see how pathetic their process is! No one has fixed my account after all this up and down and back and forth! I feel like opening a case at police station for ***** because my money is just laying with the company and my credit profile is messed!
