Useless Service

I am a Telkom Mobile client and my December bill for my iPhone was over R1000 including data bundles from Oct and R100 on texts??? Who texts anymore? Definitely not me. I contacted Mighty Mabogoane in December and I am still awaiting feedback, completely useless. I have mailed him over 10 times and he cannot assist me or put me in contact with someone who can, but mostly he just ignores my mails. Plus he only gave me a case number weeks after my initial report. I have paid the full amount as I cannot afford to be disconnected but want a rebate on charges I never incurred. I have ordered an iPhone 5S 64Gb on Smart 100 2 weeks ago, signed the contract and since then had no feedback, I need this phone for my GF as her phone is broken and she has nothing now. I have called to esquire and get told someone will get back to me but never do. This is the worst service I have ever experienced, happy to take your money but that's where the service ends.
