Takealot not holding up to warranty of goods

Start from the beginning.<br> I purchased a Speed pro ion action camera on the daily deals. After a few months the back cover had a crack in it this is the removable cover that covers the plugins. <br> I contacted ion and asked were i can have this cover replaced under warranty they offered to assist but recommended i send to the retailer were i purchased the camera for a warranty claim.<br> Before i logged a return i phoned takealot explained to the lady what the problem was she insisted that it will be no problem i can return they will send to supplier and have it repaired as it is a repairable product and that the only thing wrong was a plastic cover and the product was still under warranty. <br> I then logged a return and they collected after a few days i received an email stating that they cannot replace due to no stock and a repair was not successful thus they gave me a credit i emailed back stating that this is not the outcome i want. I requested that if they cannot do anything i want my camera returned and i will send to ion as i was told they can easily replace. Now im being told that they cannot find my camera now they want to credit me but the credit cannot buy me a new camera. So now?
