Vodacom *****S

I am shocked at how I have been treated by Vodacom!! I called at the beginning of July to have my contract (which was on a month to month for over a year already) moved to prepaid and I was assured that the number would only be switched over AT THE END OF JULY. On the 14th July, as 22h09, the number gets switched off and at 22h10 (1 minute AFTER the number has gone dead) I receive an email advising me that the number will be switched to prepaid on the 14th July and that I must make use of all the data before then. I want to know why Vodacom feels they need to act out like this????? I owed them nothing, I had paid my contract in full, and surely it's my decision to end the contract if I wish? And, why lie to me, saying that I have full use of the contract until the end of the month, but cut me off half way through - and mind you, I topped up with 1GB of data that very day.... all gone. You just don't do this to people, because guess what... next time I decide to get a contract... I'm going to MTN. I've spoken to a few people and they've confirmed that Vodacom *****s data, I never believed it before, but I believe it now. I want what I paid for - the rest of the July bill which is sitting in my inbox currently, and the 1GB of data I put on that number on the 14th July.
