Not credited

What a bad experience I have with takealot. It was my first time buying from them. I made an order on 4 September 2019. The order was with vouchers. I received an sms which said my order will be delivered on Monday 9 September before 5pm. I didn't receive my order. I tracked the order number and it says it was in a wrong location. They did tried again two times Wednesday and Thursday. It was the same story. I wonder why they fail to find my location because I buy things from other retailers but their drivers don't get lost. So I was frustrated then on Thursday on their last attempt of delivery they said they tried and they cancelled my order because of a failed delivery. I orderd two items which cost R1079. I already paid R1050 with my vouchers. I was supposed to pay the remaining fee of R29 on cash on delivery. Which I opted there on payment. Now I'm struggling to get credited in my takealot account. I already lost more than R100 of airtime calling them. Their customer services staff are not helpful. Regardless of what I tell them. One said they will credit me but they didn't. The other one said they can't credit me because my order was cash on delivery and I cancelled the order before it was deliver. Her name is Dylan Moses. I'm wondering how because I paid R1050 upfront. The remaining R29 was agreed to be paid on delivery. Now I lost my R1050 for nothing. What a bad experience I had as a fist time buyer from takealot. I want my R1050 credit in my account please
