WORSE CUSTOMER SERVICE

My mother passed away in Aug. I reported her passing and did the process of a deceased account with Vodacom on the 21 of Sept 2024- the account was settled due to confirmation I received however 3 months later her account was handed over to MBD Credit Solutions because after settlement on 24 of Sept, and Invoice was opened on the 25 of Sept - this was the last feedback I received after having to contact Vodacom. NOW, I need to find out the account was handed over due to not receiving payment and the contracts were closed, not cancelled. However, on the Vodacom app I am on prepaid and can buy whatever, make calls etc. No one is assisting me in the matter, just keep escalating it, but the last escalation wasn't even on the system. This is poor service from SAs leading cellphone network!!! I have a mail trail of 4 months of continuous forwarded proof and yet I am still being held accountable for an unpaid account??
