Vodacom really! Pathetic!

Sooo, alot of people complain about vodacom, so here is my view... I have been with vodacom for probably close to 15years and they tend to now and then ***** up enormously and then just try and shrug it off like its the customers fault. I was called by a gentleman stating that I have the oppertunity to upgrade my contract within my contract period as I am using more data than normal... I agreed, because he was right. But funny enough afterwards I realised he was not giving me a benifit and that he was just making my contract more expensive. But I agreed. Now i see on the app i owe thwn 2 months iinstallments becaise he said i only start paying end of august... Well well. This is where it becomes interesting. I signed a contract to deduct every 1st of the month. And this month nothing went off. So, as a good customer does i pay in advance I transfer money on the app to pay half of the installment they will deduct end of this month so that only the other half gets deducted... Now my account says i still owe the full amount... Vodacom, come on seriously. ***** me over at the end of this month and I will make sure i leave this network provider... I would love for someone to call me and we can discuss this "amazing" app of yours and why I still owe 2 months installments...
