Bad service

I am a Vodacom VIP red client and been with the service provider for over 12 years and for the past 3 months my account has been in a mess vodacom debit from wrong account, I make payment and then I get told I owe more than what I paid so I pay outstanding and now Vodacom is trying to rip me off again saying they never received any of my payment which Proof was sent to POP. Secondly call centre agents are really not helpful having conversations with Colleagues while on the line not asking me to hold I feel that this lady Zodwa was very rude. I asked to be transferred to someone that can assist me but still not willing. I have asked for the past month that my account with Vodacom be cancelled and still no response from cancellation. This is not how business is conducted I want nothing to do with this service provider and they teams attitude is putrid. Please cancel my account I want to take my number and business elsewhere
