Duties deducted three times.

In March duties were deducted three times from my account for the same parcel. Sent a refund form and guess what – no response, phoned them and received an email confirming they will get back to me in 48 hr’s – to date no response. This has been three months now. I honestly cannot understand how a company with such bad customer service can exist. I have stopped all my Shein and Temu orders and will not support them anymore due to the fact that Buffalo cannot even handle a simple refund.
