Bad Service from a manager, no calls returned and always on tea breaks.

I have had exceptional bad service from Virashni Govender as the manager at the cancellations department. I cancelled my dad's (who passed on in August 2023) contract on 10 April. There was a notice period of 30 days but vodacom went ahead and cancelled with immediate effect. The R292 value of airtime was then removed from the number I called back and they re-instated the number. Credit was logged by virashni as they did not reimburse the full R292 but only R150 thereof, only to find out on 6 May another debit order ran. This time the debit order ran for R324 (line rental as well as airtime (like it was a new connection).) This was also logged by Virashni. Unfortunately, on 1 June the contract renewed once again. Credit for this is also due. Still no feedback or credit whatsoever from Virashni. When I call the call Centre everyone just wants to upgrade my number but don't take into consideration that the service is so bad that I don't even want to upgrade my number. Virashni is no longer taking my calls. She is on tea breaks 3-4 times a day, every day. Never calls me back and this is not acceptable to treat older people like this as this debit order gets debited from my mom's account.
