Pathetic customer service

The most unprofessional company I have ever dealt with. They do not answer their phones, no reply on emails and when you request to speak to an agent via livechat, there is no response. I ordered on Shein on the 4th of April , paid my custom tax on time, and I have yet to receive an update regarding my parcel. I contacted ITT couriers and they have not received my parcel yet. It seems no one knows where it is!!! I am just wanting clarification regarding where my parcel is and the expected delivery date, but it seems that is too much to ask for. Shein needs to really think of using another logistics company. Unfortunately, if they don't, they're going to lose a lot of customers.
