Nightsurfer data useless, wasted all normal data and airtime, very dissatisfied

Last night 18/082017 I attempted to use my 10GB night surfer data at 12:30 am wherein it used all my normal data (350mb) and depleted R50 of my airtime. I contacted the customer service who informed me I had to restart my phone for night surfer to work. I then restarted my phone and the data still did not work. I then contacted them again and they informed me that I have to enable international roaming if I wanted night surfer Data to walk. I turned it on and my night surfer data worked. I however now have no airtime or data left following this problem which was never communicated to me and it is not my fault that international roaming was not on... I phoned telkom mobile today (19/08/2017) and spoke to a lady named 'Honey' who informed me they will not be able to reimburse me for a problem that was not my fault... How is this fair, Telkom please help me I'm really starting to regret switching from Vodacom who previously fixed a similar data problem with no issues... This is really pathetic and i would like some clarity into the no refund before I elevate this further to retrieve my airtime...
