False info given by Call Center Agent

In recent months I have been very disappointed with Telkom Mobile, in that of the lack of Call Center Agent product knowledge and incorrect information given. <br> My contract came to an end in October 2015. On 4th September 2015, I made a call to 081180 in order to find out what will happen to my monthly installment once the 24 months were up and what I will be getting. On this call, it was confirmed that I will still receive 100 minutes and 5GB data and the installment will reduce to R99 per month until I renew my contract. At this stage I was still unsure as to what I wanted to upgrade to. Thereafter, I was being charged R349 for the 5GB of data. I did query this and eventually received an SMS stating that my query had been resolved and my account has been credited. However, I am still being charged R349 for the 5GB of data every month. <br> Firstly, the agent gave me false information. Secondly, I didn't give any authorization for the 5GB to be an add on. I am totally disgusted with the service from Telkom Mobile. I would like for this to be sorted and my BANK ACCOUNT be credited with the total amount owed to me for the 5GB which I was being charged for each month. <br>
