Can the Vodacom accounts department do their job???!

I made a payment into the Vodacom account on 24 June 2022, like i did the previous month. Then this week, i started getting SMS's and an email (a warning letter) from Vodacom, telling me to pay, of which I already have. Yesterday I called Vodacom twice and spoke to ladies namely, Koketso and Mathapelo. The lines got cut off but this was after they confirmed my details and telling them that I have already made payment, the last lady I spoke to said I must forward the proof of payment, of which I did. This morning I woke up to my line being suspended! What is this??? I need my line restored, it's an inconvenience for me and their advisors didn't even bother to call me back when the line got cut off. Pathetic service! Very disappointed!
