Refund an issue for order YST348101

Ordered a dress that turned out to be extremely big because of the cut and I ordered a return for it. One of the options there was to use my own courier as return method and an address was given that belonged to the shop. Parcel was delivered on the 13th of March and Abdul who works at the shop signed for the parcel. I then sent a follow up email with proof of delivery attached asking if all was in order for the refund to happen got no response. I then called and was told my email went to some folder and they were going to get back to me. Called again next day after not receiving a response to my email only to be told Abdul works at the shop and the parcel was supposed to be sent to the warehouse. Tshepiso then sent an email to say they will organize for the parcel to be delivered to the warehouse so refund can happen. I was asked to send the proof of delivery numerous times which I did, only to be told today they cannot find the parcel. They are making it my problem that the returned dress is missing in their premises and they are doubting delivery even happened even though there is proof the package was delivered. The package was delivered by a private courier who did not know Abdul personally, and Abdul signed for the package the same way he does with packages delivered by couriers to them. They are not disputing that they have an Abdul nor do they deny his handwriting is not the one on the proof of delivery I have sent to them. So basically now I have to suffer because of their negligence. If they wanted returns to be sent to the warehouse they should have given that address. On my communication with them since the package was delivered never was I told the package is missing, all I got was confirmation it was received but was waiting to be sent to the warehouse. Communication has been terrible and if you ever want a refund do it at your own risk. Their service is not like of zando, superbalist when it comes to refunds. Learned the hard way. Done with this company and how they treat clients.
