Terrible service

Bad experience. In December 2020 i called vodacom cancellations dept to cancel my contract which i took out on the 31st October 2018. The operator that i spoke to told me that my contract was expiring at the end of January however he could not cancel the contract as it was too early that i should call back in January to cancel my contract. I accepted that. In January i called back and the operator that i spoke to this time told me that my contract only expired In JUNE 2021. To my suprise i asked her to check what was going on because my contract was a 24 month contract. She checked on the system and told me that there was a problem and she would ESCALATE the matter. I recieved a sms that the escalation was beinh processed then another one to say it was sorted. To my suprise again today on the 21 January 2022. I called and the operator that i spoke to told me that i cannot cancel now as my contract now only expires in May 2021. I tell her that is not the case. She checks the system and say i migrated in Dec 2019. I am shocked. I know nothing about this migration. I dont even know what it means to migrate. I requested a copy of the recording where i agreed to "MIGRaTE". The operator couldnt tell me why the guy that i spoke to in Dec told me that the contract is expiring in Jan 21. Vodacom is terrible. You rob is during our time of need!!!!
