I have a query with a part received

If you have received a part from a Supplier within the warranty period and you are not happy with it, 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.
