No follow up on promise

I lodged a complaint on hellopeter in the beginning of August 2015 against Vodacom Westgate about a cell phone I had purchased there. I purchased an LG G Flex 2 which was said to have 32 gigs onboard memory. They gave me the 16 gig. In August when I lodge a complaint on hellopeter, several months had already passed and they had not made any effort in correcting their mistake hence the complaint on hellopeter. They rep**** on hellopeter and promised to help me. It is now the 17 October 2015.. I haven't received any communication or resolution to this problem and I am still paying. They continue to undermine the gravity of my problem because I personally went to Westgate after the complaint and I left without any assistance regarding this matter.
