Vodacom fails to deliver

I have a Top Up Data S with Vodacom. I also have 4 other numbers with them. I've been a loyal customer for the past 20 years/ Yesterday I called to top up my data on the Top up smart S package and was told to transfer air time from my primary number to my top up data package and after that convert the air time to data. I did what it was requested but didn't work. I called back and spoke to a supervisor by the name of Ebrahim. He told me that he would do the conversion from his side. Last night I tried to connect and was successful so, I thought that the air time had been converted as promised, but, this morning I found out that in fact Ebrahim didn't do the conversion and I am sitting without the R139.00 that was supposed to be converted to 2 gigs according to customer service (Mark). I would like the 2gigs I was supposewd to get according to customer service (Mark), Please listen to the conversations. Vodacom look after the loyal customers and honour your promises.
