Lack of respect and service delivery

I logged a return on a shein item that I bought which was too big. Imile sent me a WhatsApp to notify me that it will be collected within 5 business days. Thereafter a got a text from a lady who asked if my collection address is the same as the delivery address. I responded and said yes and also notified them that I will only be back in the office on Wednesday the 25th of skins. This was on Friday the 20th of June. There after I got another text from a different number *** and I told them the same thing. On Tuesday I was called by the 079 number and then texted to say they are at the office . I rep**** and said that I did mention that they should come and collect the item on Wednesday and I even rep**** to the same text I sent on Friday. The guy sent me a rude voice note where he even used the word “nxa”. I called Imile’s customer services to lay a complaint. Spoke to a lady Sharmaine ***) who texted me after the call to say I should forward the WhatsApp texts and voice note to her to escalate to the supervisor. I did that on Tuesday the 23rd of June. Thereafter I never heard from the so called supervisor who was going to reach out to me and neither was my return item collected on Wednesday. Imile seem to allow their courier drivers to disrespect customers and then ignore complaints. They also decided to not collect my shein return item or give me an update as to when it will be collected. The other problem is the fact that they do not communicate with customers in advance about delivery or collections. They contact you when they are there without asking in advance or letting you know that they will be coming. This is very bad customer service and I’m extremely disappointed especially since it’s the first time I made use of them via shein.
