Dissatisfied with service provider Vodacom after been **** to by the consultant

I have been **** to by a Vodacom consultant on the 19/10/2022, when I called in to cancel my contract on my Router line he convinced me to keep the contract going and he said he will discount the data and make it affordable for me and would give me 15 gigs of data of which I only received 5gigs, I did make mention that I have been retrenched and don’t have the money to carry on paying. He then told me that he will also try and help me to make my account cheaper by also discounting and downgrading my contract which I agreed to but was very skeptical. He also upgraded my other two contracts *** and *** which I specifically asked him not do upgrade. I then called back on the 20/10/2022 and asked to speak to the same consultant and the consultant told me that he will call me back which he never did up till today. I then called Vodacom on the 21/10/2022 and spoke to another consultant and told her that I want the upgrades reversed which she said she will put on email and escalate it to the relevant department and up to today nothing has been done. I then called back on the 28/10/2022 to check on the reversal of the upgrades and spoke to a consultant who again told me that she will again do an email to the relevant department, and they will contact me and up to today no one from Vodacom has been in contact with me. Does it take 2 weeks for a reversal of an upgrade to be done. Any idea who I can escalate this query to, I have been a loyal customer to Vodacom for + - 15 years now and very dissatisfied with the service from Vodacom. I was not even given a reference number despite asking for one every time I called in, so how do I even follow up because the consultants are very unhelpful.
