Lies?? Where is the customer service

Lies !!! I recently upgraded end of 2022. After a few months on my new contract I found I was running low on data and air time (not that anyone at Vodacom would be kind enough to warn me of my average use at the time of upgrade). I phoned Vodacom to adjust my contract to cover my use in December 2022 and was told yes yes everything is sorted. - it wasn't and i found myself in the same situation.

I then phoned in on the 4th January to again upgrade my contract to unlimited call time and more data. The lady I spoke to said Vodacom can offer me a contract to cover my needs for R1300 a month and this would become effective in the new month - February TODAY: 1st of February and I take the time to check that Vodacom have done what they said they would. I phoned and was told 'no there are no changes to your contract' and then 'you didn't phoned in to change anything, the last time you spoke to us was 4th Jan' I asked for a service and I followed up on it - Vodacom this morning has told me I did none of this and no changes have been made???

ANSWERS PLEASE????? what is my contract now?
