**** to by supervisor re credit

I bought data for my wifi number towards the end of the month after my monthly allowance expired. Little did I know that, come the beginning of the month, my usage will defer back to my new monthly data allocation, rendering it impossible to use the data I have just bought (unless if I AGAIN finish my monthly allocation in before my bought bundle expires.) Not TCF as I have NOT been informed of this ridiculous, ********* business rule. I logged a complaint and it was agreed that I would be given a new bundle as mind had expired whilst I was unable to use it. The friendly person that assisted loaded 500MB first to check if it gets used before the bundle. It did. He then loaded the remaining 2GB. And guess what, it didn't work again! I then phoned Vodacom and had to explain the whole situation again and was again informed of the ridiculous business rule. I then said I want a refund for the 2GB. The supervisor I spoke to said that she refunded me R141 for the 2GB. She assured me that it had already been done. I asked her to put a note in the system as proof, because if the refund is not reflecting I don't want to have to explain the WHOLE story again. She ASSURED me the R141 credit was loaded AND that she will put a note on the system. Guess what? Neither was done. I went to a Vodacom shop and they confirmed there is no credit and no note regarding the credit. I would like: 1. R141 refund as promised to me. 2. I would like someone to listen to the voice recording of my last call and identify the Supervisor that **** to me and phone me advising how she will be dealt with and what her name is.
