Worst service I have ever experienced!

Very disappointed customer. From starting my account with you foschini I was told not to do a debit order as their accounts department is shocking and often takes off the wrong amounts. I am a very busy person and often don't find the time to run into malls and stand in queues to pay my account. So naturally I was late one month. As of last month (April 2016) I was due for my cell phone upgrade and was very shocked when I went in and was told that I can't get the contract I want because on experians (credit rating company) system it shows I am owing you foschini R165. I was very confused by this because as far as I knew I was up to date. So after many phone calls and much frustration I was told they only update their system on the 20th of each month and that it would take 10 days to clear and I was assured that on the 1st of May everything will be clear on experians side as they have to receive this information from foschini before they can clear it on the system. Today (4 May )I went to try get my cell phone upgrade and guess what?...they still won't let me get it because experian says on their side that foschini are still saying I owe R165!! When in actual fact I settled my account yesterday (3 May ) and asked for it to be closed as I cannot handle the foschini groups terrible service. After another batch of frustrating calls I have been told it will take another two days for foschini to update their system with experian and to top of it all off, when I settled my balance on my account I was told to pay R18,74 extra from the lady on the phone before it could be closed as it was the interest that would only be added on the 13th of this month, I am now told this was a mistake and they owe me R18,74! Does anyone in the foschini group know what they are doing? Very shocking service to say the least. Don't open up an account with the foschini group folks unless you want your day filled with frustration and long air time wasting calls. I will honestly never set foot in any of their stalls and vow never to support their company by buying any products from them ever again!
