I have not received my refund

We take this issue very seriously and can lead to a supplier being removed from the network. Your first step is to open a case with the supplier you purchased the part from. You can do this by logging into your member account and visiting the Resolution Centre. You then need to open a case with the supplier.
Once you have opened the dispute a written audit trail of what has happened will be established between yourself and the supplier. You will then need to make sure you have returned the part to the supplier making sure you have proof of delivery.
