Temu terrible customer support

For months and months I avoided falling for Temu's advertising, until I was looking for something that only Temu sold. I decided to finally order. Not an easy task, first you have to bypass all the gimmicks. When I finally ordered, I was relatively happy with my purchases. I ordered a few times, after that, and some of the products were satisfactory and others not. I decided not to fuss and return the cheap stuff I wasn't happy with, but when I did decide to return 3 products, I discovered that while returns may be "free", they are not easy. There is a specific way they want it done, and there is no YouTube video or anything showing step by step how to do it, other than a diagram that in itself is confusing. They talk about a return label that needs to be printed, but where to find it, isn't so simple. So finally I think I have figured out what I must do and pack up the three items separately with their labels in one box, and I arrange with Buffalo couriers to collect. I take it to the pickup point where I normally collect from, and I leave it there. I get notifications to say they going to collect, but weeks and weeks later, after several attempts to get Buffalo to collect, following up constantly via their app and email and even trying to get help from TEMU "help" , nothing. It is just impossible because both Temu and Buffalo use apps and bots that don't allow human interaction, so just standard questions and answers. Completely frustrating! Then to top it off, Temu cancels the return, because the return hasn't been collected by their courier! Honestly, what more can one do? Also, another thing I have come across is what I would consider false advertising. They advertise things on Facebook and if you click the LINK, it says for new users only. So, fair enough, then one tries to look for that product in the app and ... you can't find it! Anyway, I should have stayed with my gut, and stayed far away from TEMU.
