8ta Billing and callcentre agents are useless

My contract was expiring and I advised the call centre agent that I wanted to cancel it and they convinced me otherwise by giving me a option to upgrade to a sonny e1, Smaller phone but will be getting the same benefits as I was getting on my S4 (R100 minutes, 10 GB Wifi, 5 GB Telkom mobile and data: whatever the amount were) for R150 per month.<br> I agreed to this new contract, when the October bill came they charged me R693.70, I called in to find out why they told me they had not activated my new contract hence they billed me for both contracts S4 and Sonny. I asked them to fix the error and had let the extra money they wrongly debited go but to my surprise I just got a SMS saying my bill for this month is R489.50 when I called in today Notobeko assisted me and she advised that I had been double billed again as the account was not activated as per the previous months agreement with the other call centre consultant. 8ta did not stick to their promise as per the lady who sold me the contract<br> This is unacceptable after I have been recommending 8ta to my friends and family so many times only to find out they are taking money that is not due to them form their loyal customers.
