Cancelling contracts not done as requested.

Cancelling contracts not done as requested. We phoned Vodacom customer care on 20 March at 15:00 to cancel 2 contracts that has ended last year already. After 7 minutes arguing on the phone why we would like to cancel, they eventually agreed to do so. We then received a message saying our quotation has been processed (order number ***) and then 2 messages saying our request to convert to pre-paid was received and will take effect on 20.04.2023, however both messages had the same number on to be cancelled. Today I check my Vodacom app to see if the contracts were cancelled, and only the one that was mentioned on the messages was cancelled ***). The other one is still showing active with a due amount ***) and this is not the first time I requested this number to be cancelled! I would like to request my call's recording and would like to know why only 1 number was cancelled if I clearly gave 2 numbers to the consultant that day. The main contract number is *** and Vodacom can phone me on *** after sending me my call recording - ***. Werner Jonker.
