Vodacom attitude towards customers

Since 29/02/2020 I have been having a problem with Vodacom. According to them my account is in arrears but when I look at my statement on their website I am actually in credit. After sending them numerous emails and spending a total of 3 hours and 43 minutes on the phone no Vodacom employee can tell me what the actual problem is. There was 2 attempts to contact me where I was not available the rest of the time I had to contact them and when vodacom drops the call there has been no attempt to contact me. so 6 days later I still have no answers. The call center agents actually don't even listen when you explain the problem to them every time I had to stop the agent from talking and explain my problem to them again. All they care about is telling you what they have and not listen and look for the problem. And here is another issue they have now given me 3 different dates for my upgrade 2020/02/29 ,2020/03/02 and 2020/04/30 And guess what they cant answer that question either. I would love to upload all the screenshots downloads and sms I have received from them. On my previous online upgrade I waited 2 months for my device with no contact from them. only when I contacted them and stated that I want to cancel my upgrade and contract I received information on my device and 2 days later received my device. I have been a customer of Vodacom for 20 years and this is how they reward loyalty. They don't care about their customers at all. I am very doubtful that this review will change anything because they are not interested in solving the problem they just care what they have in front of them not at what the customer is receiving. Guess it is time to change service provider and I would recommend that every single vodacom customer I cross paths with
