Annoyed loyal customer

The 1 star above is not deserving, but I cannot select a minus 10 I have made at least 15 calls, many many mails, etc to the cancellation division of Vodacom where I have had been a customer for 27 years. When I wanted to change my expense business package, Red Advantage Package, to an more affordable contract, I was still charged another package over and above the existing one in December. I was then assure all sort of promises, but yet again, I was charged again on 31 January for I am not sure what!! Yet on the Vodacom app, I have zero minutes and zero data left for February. Even though I was assured in December, that me leftover minutes will be valid for 60 days. Yet another empty promise. Every time one tries to phone again, you end up with a different person, and nothing is resolved. You go to a Vodacom shop for assistance, they tell you to phone the cancellation number, back again to square 1. What has happened to Vodacom's great customer service from years gone by.!! I am a very frustrated annoyed customer. I
