Edgars Sucks

About a month ago I realised that I was being charged for a Data Sim card by Edgars and this has been going for quite some time. I always paid my account and never questioned it as I had constantly made purchases at Edgars on my account. When i realised i was being charged for items i never requested, I called immediately and asked for it to be canceled and for the transactions to be reversed. I was asked to RMCS and they advised that they will cancel it, initially they did not and I had to call back a week later and it was eventually canceled. I questioned the reversal and they advised that they will find the recording. I called back 2 days later and was advised that they have the recording and someone will call me to listen to it. I called back the following week asking when i would receive feedback, i was advised by a lady on the call that she will listen to it and call me back. She then called me back and said they don't have the recording. Between all of this, i receive daily calls from Edgars advising me that i owe them money and i have to explain to them the same thing over and over. This is the worst customer service i have ever experienced. I have told them countless times that I will pay what i owe once they do all the reversals and if there is actually anything left for me to pay that I would pay it immediately. I do not have an issue paying my account as I could pay it right now but why should I pay for something i never took out with them and then have to wait another year for them to reverse it. They need to sort this **** out immediately as I am sick of the daily calls and them threatening me with it affecting my credit score. It can affect my score but they will have to fix afterwards as I will not pay for *****.
