I was looking to buy headers for my motorcycle (item detail : 71661MI arrow headers), I noticed on the website they mentioned to contact them to ask if the item is available before placing the order to ensure availability and confirm delivery times.
So I emailed them on three different occasions (please see attached document for email trails). I asked them clearly if the item was available to order and they told me that it was available and advised me to order it and reassured me that the item will be shipped within 3-4 days.
So, I placed my order for the arrow headers, received my confirmation email as a standard no issues at all till that point. Four days went by and I have not received any email confirmation or any update on my delivery date, so I contacted them for an update.
They said that the item was not in stock and the order was sent to arrow for manufacturing. I was shocked when I heard that because I asked them before placing this order if the item was available as mentioned above.
I only placed this order on the basis that the item was available and from experience I know that ordering an exhaust might be a lengthy process and can take several months to be produced and shipped which I tried to avoid hence I emailed them prior to placing this order.
When I confronted them with the emails I’ve sent prior to placing the order, where I asked if the item was available, they basically replied back saying that the shipment will be ready in 3-4 days not the delivery. I struggled to understand their concept what’s the difference between shipment and delivery.
They clearly manipulating and misleading costumers with wording which doesn’t actually make sense in English, please see email trails attached.
Since I find this situation unacceptable I asked for a full refund because I don’t want to wait , they got back to me saying that if I need a refund they will cut 20% of the total amount as they already placed an order with the manufacturer and asked me to read T&C. They basically gave me two options either wait or take a 20% cut.
I believe that they are clearly manipulating people to place orders when the items they sell don’t physically exist by lying to customers and playing in wording. By imposing their 20% cut refund policy they push people to wait indefinitely for their orders. Most manufacturers are not operational at the moment which means I am going to be waiting for at least 2 months to get my order. If I knew they don’t have the item in stock I would have never placed this order.
I never seen anything like this in my life it the 21st century this shouldn't be happening to customers, feels like I am dealing with the mafia, taking customers money by twisting their arm.
I don’t want this to be happening to anyone in the future as it can make you really frustrated and get you down.

For the record I received my item after 17days which was better than I thought but again they need to change their wording on their website as to many similar complaints which is clearly an ongoing issue with other customers.
