Billing

My contract was due for upgrade in February 2016. I received a call from a Cape Town call centre offering me a Huawei P8 lite including benefits of 1 Gig all network, 100 minutes call time, 10000mb wifi data for R199. I accepted the contract as it was cheaper than the previous one that I had and was looking for something cheaper and affordable. I received a bill stating that I need to pay more than R670 I called the call centre enquiring this amount the consultant told me I was billed for a hole lot of things I did not sign up for or agreed on she said she will log a case for me in order for them to reverse certain charges that was added. She also mentioned that the contract I took plus benefits is actually R320 and not the R199 as this is just the amount for the phone without benefits and that is not what was explained to me when the phone was sold to me. I was told the billing department has a turn around time of 48-72 working hours which is 7-8 and that I have to wait for 8th day in order for my query to be resolved. Which is too long this is my 3rd contract with telkom mobile and definitely my last I cannot afford to pay more than the R199 per month or else cancel the contract
