Account Complaint

I app**** for a new WiFi contract over the phone at Telkom, the telesales person informed me that they are going to deduct am amount of R299 for my account to check my banking details and if funds are available which they did on the 04 February 2016. I received my device and sim card on the 16 February 2016, and when I confirmed my data use aged on the 19 February 2016 there was only prorate data given to me of 5 gig instead of 10 gig of data as per the contract. I paid a full months installment but only received half a months data. And on the 04 February 2016 I received a sms that offerd me a new deal a Telkom of 10 gig and 300 gig night data for R249 per month, I immediately phone the telkom telesales department to confirmed the deal which they did not know of, the guy helping me said I just must reply yes to the sms and someone will contact me, in which case I can change my application to the new deal. Nobody ever phoned me back.
