Query: Absolutely Terrible - Do Not Use

I ordered 5 x Parker Ballpoint 0.5 mm Blue refills but received 5 x 0.8 mm Blue (ie the wrong size). I wrote to the supplier advising them of the error and asking how I could arrange for a replacement/refund but after mroe than one week have receievd no response. As at the time of this review I am yet to receive a response from the supplier. In my view this is terrible customer service and I will never buy from this supplier again.
