Unbelieve at such atrocious service

FOUR MONTHS SINCE MY INITIAL CONTACT!! AND STILL NO FEEDBACK FROM VODACOM? I HAVE NOT EVEN RECEIVED A TICKET NUMBER!! On 28 February I contacted Vodacom and was referred to their Retention Department. I have been paying for many years as if I had a handset contract and was offered a package of 5 Gig data and 250 minutes for R132.00 per month. I accepted this offer. Smart M+ I noticed in March that I am still on the original package, and called in. Was promised it will be attended to. Nothing happened in March. I called again in March, was again promised it will be attended to. Again called in April, was again promised it will be attended to. Called in again in the beginning of May and was then told that Vodacom has ‘difficulty’ changing my package to the new offer, as my number is on the ‘old system’. No solution was offered and the lady that I spoke to was pretty much disinterested in my problem. I have now been paying over R500 per month, for 3 months, and unless a miracle happens, will be paying for more months on the old package as if I am paying on a handset. Firstly, I cannot believe with all the technical skills at Vodacom, that not one of those techs can find a solution. Secondly, I expect this to be resolved without delay. Thirdly, I expect a credit to my account for all the time that I am forced to pay the amount exceeding the R132.00
