Useless customer feedback!!!!

I have 3 numbers with Vodacom for years know. Two of my contracts was renewed on the same date. My main contract has 20G data on for more that 4 years know. This changed without my consent or approval to no data. This is the second time Vodacom makes this mistake and it is absolutely unacceptable. I locked a complaint by phoning in 2024/08/08 RC*** . Turnaround time of 7 days was promised. On the 12th of August I received a mail from your guys saying that you will come back to me within two working days. I replayed on that mail 19th August, 7 days later. Today 23rd still no replay form Vodacom since a logged the com plain first on 2024/08/08. This really useless service. I took a screenshot of my account status Wednesday afternoon 21 August, that show that I do have data, the next morning I took a screenshot again, and then I had no data. I do not understand this at all. Some had to be working on my account during that time. Can I please have this sorted out ASAP!!!!!! I blows my mind that if you don't pay your account, Vodacom quickly sort you out with a remainder to pay, but you can't follow up on complaints. Absolutely useless!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
