Bad Reurn Service blamed on Customer

I have always only received good services & quick deliveries from Takealot.com. But Experienced very bad service recently with a return. Nov2018 I returned a refurbishes iPhone that I purchases Jan2018. It was not coming on since Oct2018. I wished for it to be credited to my account or sent to the supplier to fix. After no response on the item send back I checked my status after 2weeks on the app and saw Takealot it awaiting the accessories. I phoned them to confirm this and they collected it. After 2weeks still no reply. I phoned several times to confirm that they have received it but with no replies back from the workshop. Dec 2018 I receive my phone back - still defective without accessories. I had to phone again. They had to collect the phone again, because the accessories is still at the warehouse. After numerous phone calls and no replies back from the warehouse regarding if the phone & accessories have been matched up I get a email 30/1/19 the phone is out of warrantee and the comment section states "Customer delayed sending accessories" I arranged pickup the moment I phoned to find out about this. I am very upset that they are blaming me if they are the culprit's!! I don't mind not getting a credit. But at least send it to the supplier. I will even pay for the repair. But don't delay things for 3months and then blame it on the customer!
