Over billing, Contract wrong, Accessories not recieved and pathetic service

I did an upgrade in May 2017 to date i am still waiting for my accessories,Agents team leaders and managers is just ignoring me . I have logged numerious calls with customer service and nothing is resolved . My cell phone account is billed in correctly every month and when i requested a copy of my contract my monthly payments is not what was agreed upon at the time of the upgrade .I was contacted by KABELO MOLUSI on the 10 October 2017, making all sorts of excuses for MAGDALENE who was the person who assisted me with the upgrade , he claimed that the accessory kit that was on offer that time is no longer available but offered to give me airtime of R1200 to compensate for this and when i told him i needed to think this over he told me if i dont take this offer immediately it wont be avaialable the next day , i told him not to threaten me and that i was not the one at fault. I emailed him the next day informed him that i wont be taking it cause i dont need airtime and that they can pay the money over so i can purchase the products, to date no response from him as well. I am billed for 2 then 3 handsets every month and i only i have 1. Every 2nd month a credit will be raised on my account but nothing is ever done about the incorrect billing. On Friday 24 November 2017 my service was suspended due to my account being in ARREARS; this was just enough . I called again and was given all the excuses again having to explain everything to the team leader that has happend for the past 6 months and she (MAMOKETE ) vowed to call me back on monday between 9-11 i am still waiting for her call. I then phoned again (once again had too thru the whole process) and then i spoke to MINAH who was also not able to assist me but also vowed to call me back on Wednesdays still no call ; so I again phoned in again and then spoke to Munga and she couldn't give me any info cause the upgrades dept is close (i lost it with her ) Vodacom have *********** staff so eventually i spoke to Pindile who now also vowed to call me back tomorrow with feedback ...i am sick and tired of the pathetic service and i know this matter will persist nothing will be resolved and i will be the one that sits with a blocked phone and cellphone account that is in arrears. Last ref no. ********** ********** 7
