What a ridiculously poor service

I wanted to make a bet online. I deposited R20 on Saturday using OZOW, which is one of their payment options. The R20 did not get credited immediately,but my bank did charge me for an immediate payment.I tried to get them to allocate this,I sent them a proof of payment twice already, but I have been getting nonsense feedback. I get a different reference each time I follow up, but there is no action.this is an absolute poor service I have ever seen, if they are struggling to allocate a stupid R20, what happens to those who want to claims thousands that they have won? I have used OZOW when making online payments with other merchants,the funds are always processed immediately,but it's a different story with this one,it looks like people who work there don't know what they are doing.
