IMILE logistics and Courier guy transport poor service

I have had an extremely disappointing experience with this service. I am currently in Rustenburg with a parcel that needs to be returned to SHEIN. IMILE was assigned to collect the parcel within five days after the return was logged with SHEIN on 01 April. To date, the parcel has still not been collected. On 07 April, a Courier Guy company driver was sent to my address without any prior notification or call, after which the collection was cancelled because I was not home. Since then, I have made several attempts to contact IMILE for assistance. Unfortunately, calls are either left on hold indefinitely without being answered or do not connect at all. Communication via the IMILE WhatsApp line has also been unsuccessful, as it only connects to a virtual assistant with no follow‑up from a consultant. The experience was extremely poor and does not warrant a one‑star rating.

Given these challenges, I would like to understand why SHEIN does not make use of Buffalo for returns collection, as they were the courier responsible for delivering my items.

Please advise whether there is a return hub in Rustenburg where I can deliver the parcel for return.
