Ive inquire an item a specific model number of their availability in their inventory, they told me they have ************** their warehouse. The item I want was Winco RW-S450. Id need it in a hurry and then proceed to order 10 of them. 1. It was indicated that it will be shipped out ***** hours when in stock but Id had to chased them down before it was shipped.2. After a long wait delivery came and they sent an incorrect item, they deliver Winco RW-S451. Id called them and they told me everything in their system shows it was for 450 and not *****. They then came back telling me that 451 is the same as 450, it is a similar product. I did not authorize any substitution of my item, I ordered 450 and that is what I want.4. They lie once again telling me that it was shipped from the manufacturer, which initially telling me from their warehouse.5. I requested that either they send me the correct model or I will need a refund. They told me that I need to pay for shipping the wrong items back to them and once they get it then will issue me a refund. It is not my mistake as I did not get the item I ordered nor did they ask me if I can accept 451 i/o 450. There is no reason for me to be. responsible for shipping return if they are at fault.This company is a scam and has threaten in not giving me a refund. They lie from the start.
