Bad customer services

When companies have to pay you back it's always a big problem. They quick to say if you don't pay the VAT your paid for goods will be returned. They can email you call you multiple times, but as soon as they need to make a REFUND then it takes months or never. Spoken to so many people but just not getting my money back. I will never buy online again and make sure I inform Tume and Shein multiple times about Buffalo bad services.
