Takealot really disappointed this time

I have always been very happy with the takealot service but recently I experienced an issue that have not yet been resolved. I found that the communication between the call centre and the warehouse is non-existent. The call centre sent an email to the warehouse to escalate the issue. And it has been a week now and they are still waiting for a response from the warehouse regarding my order that was collected by Fedex in error. I now sit without an item that I ordered and paid for in full. I placed an order on 18 September 2020 #***4 for the Garmin Vivoactive 4S Sport Watch Black and slate. The item was due to ship on 22 September 2020. I logged a return for this item. I also called the call centre and they cancelled this order for me. the return was never cancelled - Refer RRN-fd99-f668 and RRN-2b42-fb46 relating to the same order ***4. A credit was app**** to my account. I used this credit on 22 September 2020 to place another order ***8 Garmin Vivoactibe 4S Sports Watch Powder Gray with Silver. this item was delivered on 23 September 2020. On the same day Fedex came to collect this item which was the return relating to order ***4 that was never cancelled. Now my order ***8 is at the takealot warehouse and no credit has been passed on my account. Please either return this item to me or issue me with a credit so that I can reorder the watch.
