WORST SERVICE EVER!!!!!

I have been told from my Branch in Somerset West Mall - that i will receive the 30gig data (10gig per month for the first 3 months) and unlimited free mtn to mtn calls (for the first 3 months) when i do t upgrade that was done on the 25th August 2017. Monday now and i phoned the call center which stated that they must first log a equerry to check that i am on the correct contract to receive this special where the call center team leader Mohlake Baholo (Customer Care Team Leader in Durban) stated that all mtn new and upgrade gets this special. I am not happy about receiving such bad service and i have the complete call recording on my side for reference - reference number the to call is ********** 60/ The team leader also stated that he cannot provide me with the recording of the call when asked but didn't say why (BUT we are on a VoIP system) with 24 hour calls recordings. I cannot believe the bad service MTN is giving to the customers and treating them like fools. Sorry but i am going to cancel my contract because of lies and a team leader that tells me he will FIX my problem by escalating the matter.Escalating the matter doesn't FIX the problem.
