No feedback from credit controller

My mom was contacted by Edgars to join the VIP programme, due to her being a valued customer. Nothing that was promised transpired. My mom only ended up with a account that just piled up without her reaping any benefits from it. My dad advised her to get the VIP benefit cancelled. After numerous attempts and mom ended up paying an amount of R226 any cents for nothing, we managed to have it cancelled. Then there was still the matter of the mobile content that had to be cancelled. My mom tried to have it cancelled to no avail. Ladies at the Customer service tried a couple of times. Then I got fed up and on the 9th of Sept 2015 I asked the lady to cancel the mobile content, yet the mobile content still reflected on the account. When then paid Edgars another visit. They attempted to cancel it and to have the account credited. Every month the mobile content reflected on the account. Every time we had to visit Edgars again with the same scenario. In Dec 2015 we were told it will take 6 weeks to be credited. We visited Edgars now after 6 weeks mobile content still there. Akira promised to resolve. She promised to phone my mom today, she did not. 7 visits to Edgars, no joy. Close account
