Bad Service and debiting customer twice without permission

On the 17th Dec 2017, I placed an online order for good as advertised by Toy Adventure, by checkout time all products were listed as "in stock" and full payment R 4,038.60 was taken off my account via www.payu.co.za.

The next day I received an email from Toy Adventure notifying me that there were two items not available from my purchase list (not the first time as this same issue happened twice before as well) and that they will only take the new total of R3,730.60 from my account......

Instead they took both amounts from my account, when I managed to get hold of their customer support I was first placed on hold for 15min and then told that the R4000 will be "reversed asap" on both the 19th and 21st of December I requested and update on the release of the R4038.60 initially taken from my account and again I received no clear or definite answer on if and when the hold they placed on my money will be taken off.... all further attempts from myself to get a resolution on this matter has been unanswered or ignored.

Please whatever you do, don't ever trust this company with your Credit Card details or with the trust that they will put you the customer first.
