VERY VERY BAD CUSTOMER SERVICE!!!!!!

Unaware of it, I was issued with two monthly magazines in 2014 whilst the SA Post Office was on strike. I never received these magazines until the strike was over and then I received various envelopes with each containing two magazines in it. When I looked at my accounts I then also received, I noticed that I was charged for it. Upon enquiring with Customer Services via e-mail I was told that my account number was incorrect, I was then asked for my ID number and again I was told it was incorrect. As I have been out of work since September 2014, I tried to keep my telephone calls to the minimum and I then personally approached the manageress at Foshini at The Glen. I was told that these were issued for 8 months. I went to see he at least three or four times and have spoken to various other members of Foshini staff on the phone. Everyone I spoke to said the balance will be written off. In the meantime, interest was added every month and I started receiving threatening SMS's from Foshini and now have been HANDED OVER. I want this sorted and my record CLEAN. I request a senior manager to phone me and sort this out URGENTLY
