Onedayonly Customer Service cannot read

I really am struggling to deal with client liaison as they DON'T read emails properly. I ordered masks #230441 where I spend R178.00 of my R500.00 wallet credit. The order was short delivered. After back and forth and countless delays and correspondence that was NOT read, (#846125) it was decided to credit me for the order. This was verified by Team Leader Jane. Since I had used part of my credit I asked that the amount be returned to the wallet. This has not happened. I emailed about this (#895944) and a very helpful Jason Witbooi informed me I had a credit of R322.00 Very obvious that my email or the thread had not been read or understood. My levels of frustration are thru the roof. First the order was short and my mail WAS NOT READ. I wasted time explaining even after sending images to only receive confirmation that the order had been dispatched. A trend of NOT reading the customers email follows...

Who can I speak to or contact that will either listen or comprehend what I am writing?
