RAIN IS *****ING FROM ME

I received an SMS in May to upgrade my then 4G account (R479) to a 5G plan for R 499. I was quite okay with the 4G plan until RAIN's message. I quickly completed the application and immediately paid the R499 on 27 March even though they had already debited my account with R 479 on the arranged debit date. The router was delivered, but not for one second did I ever get 5G data. The 4G was, however still available to me, so I used it. Upon enquiring with them...IN MAYA AFTER STILL HAVING NO 5G DATA,, two ladies, attempted to connect it, but did not succeed. On 21 May, they sent out a technician who struggled so long and eventually left with the 4G SIM, so from that day I had absolutely no wifi. It was also made known to me that the 4 G account was still available, which was not supposed to be the case, as THEY had offered me an upgrade from the 4G plan. I sent the proof of the SMS to 2 people. One of them being Ndumiso Nxumalo, who wasted so much of my time taking notes, and recording all the steps that had already happened by them. Upon following up, he did not even have the decency to respond. The next load of empty promises were made by a lady name Muriel who swore high and low that she has escalated the matter, and will provide feedback. The minute I demanded a refund, her tune changed. Still I wait. My problem at this point is they have received a R 499 from me for services not supp****. Over and above that, they debited R 958 from my account on 25 April and then again on 25 May, after they removed their SIM from my house. I was lucky enough that they skipped me in June, but now they have debited my account again on 25 July.

What do I have to do to get them to finally close this account, as instructed on numerous occasions, and when will they stop *****ing from me.
