Vodacom Customer Service Failure

I have been a loyal customer for 27 years with 13 different contracts that I have never missed a payment on. I have been struggling for 6 months to cancel some of my contracts that have ended. I have paid the cancellation fees only to find out that it was not processed. It is now 8 weeks later and still no response. No mail, no call. I have been blocked to the call centre as spam due to amount of times I have to call for assistance. My account is still on the old Legacy system and not all agents have access. This causes that someone needs to call me back. This also never happens. Just sad that they are so quick for new business, but if you are in a financial tight spot, nobody is willing to assist. I have 3 adult children that want to take control of their own contracts and I am not receiving an assistance. I live in a remote town and do not have access to a Vodashop, therefore forced to call the call centre and hold for up to 20 minutes. Treat your loyal customers well! Should get VIP treatment for 27 years!
