Vodacom is pathetic

I went for my upgrade on 9 January 2018 and all the info and uploads were done on a TABLET. On 14 April I get an email from the branch manager at Vodacom Greenstone store, saying that my upgrade didn't go through correctly and will I please sign the attached contract and send to him. Which I did. They had changed my package to a Smart S Top-up. So now I have huge amounts of data (which I don't need) and run out of airtime every month. I went into the store last week Thursday (26 July) and Michael helped me. Sorry cant do anything till 3 months have passed. From 14 April till 26 July is longer than 3 months but not according to Vodacom. Michael told me to phone him on 1 August and he will advise me of the new package deals. I phoned Greenstone on 1 August and it was Michael's day off!!!! I then proceeded to phone customer care. I was advised to Google the different packages and call when my husband is at home (the contract is in his name) and state what package we want to migrate to. We did this - only to be told that it will only be effective 1 September 2018 as 1 August is already passed. (It was still 1 August for everyone in South Africa except Vodacom). I told the agent I am not accepting this and was told I should have done this 3 days earlier. Vodacom should start training all their agents and sales people to sing the same song. The agent said she would escalate to the SOLUTION EXPERTS. I received a reference number: 1- ********** ********** . I received another sms yesterday saying the same thing. This morning I decide to phone customer CARE to find out when the Solution EXPERTS will actually speak to me and was stonewalled by agent Sibonile Msipi saying he has to do security checks with my husband AGAIN. He would not even listen to my reference number. VODACOM............
