Poor service and quality

I have processed according to their system 6 return items from 4 various orders. This was 2 weeks ago. The have not arranged for a collection at all??? My first return is about to lapse. You cannot communicate with them as you only hav a stupid bot. Shein collects refund or return request the same day!!! The quality of Temy articles are also getting poorer., You add an item to you cart and whilst in your cart they increase the price?????
