Extremely dissatisfied Vodacom customer

Vodacom has the worst customer service. I made an online deposit (R550) from my Capitec app on the 30/03/23 to Vodacom. It has been two months with countless calls to Vodacom customer service as well as visits to the Chatsworth Vodacom store. It seems that no one can assist me as the Finance department is unreachable. I need to cancel my contracts next month and I know that this unallocated amount will be used as an excuse not to cancel. I am so frustrated.
