Deceptive marketing and sales team - Appalling Customer Service - Lack of Care - NO FOLLOW THROUGH

I request a migration from Smart M+ to a Red VIP 3 months ago - I saw the online price of R1199 line rental only. After calling in more than 5 times for the same request and going through Escalations each time receiving a RESOLVED notification on the My Vodacom App I finally managed to find someone who could get this done. The Discussion on the Phone was that there would be a line rental charge of R1199.00 and that my Handset amount would be above and beyond this and that the Migration would take effect from the 1st October. As I was running out of Airtime I bought a further 500min to take me to the end of the month. I had a recurring 10gig data which I cancelled at the same time as the data I had would carry me to the end of September. The next day I noted that I had been migrated to the Red VIP package - I queried to resolve this as in effect I had just purchase 500min that would be wasted as the agreement was Migration from the 1st October at R1199 line rental. Come the end of the September Month I was charged Line Rental for Smart M and Handset. Come October month end I have been charged R834,32 ex Vat Red VIP Line Rental for September and R1564,35 ex Vat for October Line rental. I have contacted the Call Center at least a further 2 times( I am currently on hold and been on the phone for about 55min) Call Center tells me that the Line Rental I am paying is R1799,00 which is not what I agreed on the phone....best yet is that they have sent for the FIRST TIME the Quotation indicating the R1799,00 line rental which apparently they were meant to send before doing the migration. All in all I have been trying to do this migration for about 3- 4 months. I feel that Vodacom's customer service center hide behind the help desk number. I have asked on multiple occasions to be included on mail in the escalation but have been told that this is not company policy.
