Poor service/not listening to customer/not resolving issue

I upgraded from the red package to red plus 2 months ago. Since then I have had intermittent cellular data. I have phoned on numerous occasions and have been into the Benoni branch three times (the staff at lakeside were extremely helpful) but are not able to resolve the issue. When I leave a WiFi area I have to on numeorous occasions turn off/on my phone to reactive cellaural data. I have been a Vodacom customer for 20 years and am on a red plus package. Vodacom doesn’t seem to care about the customer!!!! I previously had to have my phone exchanged as the phone jack did not work. They did not start a new warranty with the exchange and now expect me to send my phone in to be checked - another trip to Vodacom, more inconvenience and I will have to pay if there is a fault. I am a professional and my phone is an integral part of my business and can it be without cellular data when no in a WiFi zone. There was no fault until the day they upgraded my package. This excercise or back and forwards to Vodacom has cost me cost and money and we have no resolution. Choose an alternative service provider and don’t choose Vodacom!
