Credit of R3003 on a data bill

I recently did a large game update for a newly purchased game. I waited until midnight to take advantage of my Vodacom night owl data. I still did not have enough normal and night owl data so I purchased another once off bundle. Unfortunately I went to sleep before waiting for the confirmation sms that the bundle had not gone through.<br> I woke up to the shock of the download going out of bundle meaning I was billed R2 per mb rather than the bundle amount of about 15c per mb. This translated into a R3502 data bill over and above my normal cell phone and data bill.<br> I called Vodacom and asked if they may give me a discount on the out of bundle data as it was off peak. The call centre agent lodged a query and the data department called back a day later and said they had audited the data and my account had not been hacked and I definitely used the data. I told the person that I was not disputing the usage but was asking for a discount. She then proceeded to give me many tips on how to prevent data usage which was reinforced in follow up sms's and she proceeded to credit R3003 of the bill and I was effectively only charged R499. Called a once off good will gesture for a loyal customer.
