Most disappointing service I wish I could distance myself so badly

Vodacom worst ever,please do not do vodacom insurance ,they cancel insurance and increase insurance without informing you,they have access to your bank account so they change the debit amount to what suits them ,I had comprensive ehjch I took because I could of afford it and then vodacom decides that the comprehensive insurance which limits me my claim to 15000 is not good enough I must have unlimited insurance where I can claim how much but at who cost ,I signed a contract and I chose that contract and that option that limits my claim to 15000 because.iphone 13 so now I must pay 400 for iPhone 14 ,4000 rand per year extra on cellphone insurance because vodacom feels the need to change my contract without informing, becareful when you upgrade the vodacom agents tell lies they say you will.not pay for upgrade but when you get your bill you see there upgrade cost ,fo not take contract with vodacom they ***** from your bank account, now they charge me extra on my insurance and the accounts department says they cannot help because they nog insurance department then transfer me to insurance department, get to insurance department they explain that no extra money should be deducted from my account and should be invoice and then will return me back to accounts department so I can ask them to remove it off the invoice,u must ask for it to be removed but I was not consulted when it was added,then accounts states that I will put youvthrough to customer service then you can ask them to transfer you to accounts, really I got to do all this unnecessary back and forth because vodacom wants to ***** my peanuts oug of my bank account thinking that I am someone who never checks my statement, vodacom you don't just disappoint ,your ppl you are *********** ,there queries that still not resolved since last year,vodacom says you can request a recording I asked for one till today I have never received the recording and have never had feedback from my queries regarding all the incorrect information given before I upgraded,terrible, I count the days until my contract ends
