I CANNOT CANCEL MY MONTH TO MONTH SUBSCRIPTION

I have been trying to cancel my contract since February. My contract expired in 2020, so I was on a month to month basis. In February I phoned Vodacom on 135 to ask to cancel the UChoose Flexi 125 subscription. The consultant canceled this but offered my a 1GB data bundle instead. I agreed to the data bundle as it was a good price, but he needed to cancel the airtime. Which he did (or so I thought). He did however cancel the Caller identity on my wife's phone - which I didnt even ask for. So in March - I am sent a bill for the Flexi 125 and the Data bundle - and a charge for Feb data, he said it would start in March only!! As I had inserted the sim card into a modem I didnt know of the airtime until I got my invoice in March. I then phoned 135 again and spoke to a lady - she humbly apologized and promised to cancel both as I was not impressed that this was such a mess up. Now comes April the 1st - April fools joke - I was given the data and Airtime AGAIN. So now instead of my account costing me R 55 a month (which it actually been invoiced at R 58 incl vat) I have to pay R 242.71 a month - for something I cancelled twice. POINT 1 - I expect the full account to be credited for the airtime and data for March and April. I have not touched the airtime - so hopefully you can reverse it on the phone, same with the data. I do not want the data contract now on my number ***. POINT 2 - the one thing that was canceled is the Caller Identity on my wifes number to be put back (her number) ***. The sim card *** is inserted into a modem which is off, so if you need to contact me please use *** (my daughters phone) to sort this out. As I am a pensioner I have been trying to cut costs. This stuff up from your side will probably cost me more than I can afford.
