Vodacom fibre billing system questionable.

I wish Vodacom, which declares healthy profits each year would reinvest into writing proper apps and billing systems. My fibre line keeps being cut off. Vodacom does not seem to know what the balance on my account is. My Vodacom statement on the app shows Vodacom owes me R769.00. I contacted the call centre who can’t help as she can’t see what is going on, I need to speak to billing, I am told, who only work weekdays and take 48hrs to respond, so my line, with public holidays will be down for 5 days. I asked the call centre if they can send me a statement from the beginning of my contract so I can reconcile the account and they said they are not sure if that can be done… In 2021?? This is supposed to be a tech company. What is the purpose of an app if it can pro you with the most basic information about the account? My advice to Vodacom is to take down the app until they get it working properly.
