Mistakes are made at Head Office

I have been a Cell C customer for several years. Every time my contract is renewed I have trouble for several months to sort out the new payments. Exactly the same thing happened this year January. I have two numbers (phone and internet data) that were always deducted together. This year they split the numbers and only charged me for the phone. The data number isn't deducted, my internet access is cut off and I have to go to Menlyn to pay it in cash. Every time the consultants contact head office to combine the 2 accounts, but it isn't combined. This has been happening every month since February. I already have 8 reference numbers and the problem is still not sorted out. Instead of combining the 2 accounts a third account was opened beginning of July! I just received yet another email saying I'm in arrears again. I e Every month I'm under the impression that the problem has been fixed. Is Cell C really unable to fix such a simple thing as combining 2 accounts to be deducted together at the bank? The people at head office don't listen to what the consultants say to them. I waste my time every month to sort out mistakes Cell C make, which they are apparently unable to fix. I am at the end of my patience with Cell C. Just fix the mistakes you have been making since February. I am a very unhappy customer!
