Worst Customer service!

I had 2 contracts with Vodacom and contacted them to cancel on 22 September 2020 as the 24 month contract came to an end. The customer care agent from the cancellations department only canceled one contract, I called over 10 times since then and have been given the same answer, “I have escalated the matter and someone will contact you.” Today, alone I made 4 calls, eventually someone told me that they have canceled the contract and they app**** for a refund. I only got a reference number but they sent the sms regarding cancellation to another number of which the contract expired so it’s no longer in my possession. The service from Vodacom is atrocious, for them to treat loyal customers so badly is absolutely disappointing and at worst they will lose customers due to such bad service. If they don’t have proper processes in place then a contract should automatically be canceled after 24 months, customers shouldn’t have to call over 10 times to cancel a contract. I even sent a message on Facebook, they are quick to reply to a comment on their page but no further action is taken.
