Worst experience ever

Poor service I have paid for customs on the 16th of May for order to be delivered when check the status it's still stuck on taxes paid when I try to get hold of them it's stories when I check my waybill the arrivals dates of the order they change everyday, secondly I mistakenly paid for an order that I was refunded by the supplier of which is Temu. When I ask for a refund at Buffalo they tell me I should contact the supplier whereas I paid Buffalo for customs. AM NEVER PLACING AN ORDER AGAIN...
