Vodacom shocking service!

Once again, shocking service from Vodacom! This time they neglected to debit my account at the prescribed date, then they proceeded to send me rude, demanding voice messages and SMSs, demanding that I pay an amount or they will cut me off. After at least 3 calls, I found out that it was their error so they agreed they would debit my account on 13 August. Then on 17 August I got a notification that they had billed me again! On calling I was rudely informed I could get the money returned in about 7-14 days or apply that amount to my next bill. Really? That's how you solve this ... by *****ing my money and telling me I can't get it back for 2 weeks! So I go online to see if I can buy more data and ... voila! They have blocked my account saying I am in arrears! Brilliant Vodacom. You suck big time and you have just used your last get-out-free card. I WILL be moving to another service provider!
