Bad customer service

I am getting tired of vodacom. I have been crying about the unnecessary charges that they have charged me. Now I am expecting to upgarade. On their voice prompt it says am upgrading on the 1st November 2019. Now the consultant is telling me 2021. And my last upgrade was 2017 july. I am told that my month were increased due to suspension of my line. And as far as i know the months that i skipped I made arrangement and pay arears back until my account become up todate and continue with monthly payment. And i was told that my contract was suppose to end in April this year. Now they are saying is ending next year 2021. What am I paying for. The phone that i took in 2017 it is suppose to be paid until 2021. Were as i was told that i finish to pay my phone last year am just paying for airtime only and my upgrade is in November. This whole thing doesnt make sence. I even try to apply for another offer and they are declining everything. Tell me what am I paying for exactly because as far as i know i dont owe vodacom and were i was owing i paid back. And were they charged me unnecessary they took their money. If you dont want me to be part of vodacom can you kindly cancell my profile with you because i am always crying with vodcom and to get help i must make 50 calls first. I
