Since Comet was taken over from the Kingfisher Group, things seem to have gone downhill a little.
I purchased a printer from them, as it was the best offer at the time on-line. I saw the printer, wanted further information so I contacted the phone number listed [call centre]. The call centre gave me the information, suggesting that they would arrange for me to collect the printer from the local Comet store at the website price. I arrived at the store with the information that I was given, and utter confusion resulted. Eventually after an hardened discussion, the stores duty manager conceeded that I could have the printer at the agreed call centres instructions. Never again.
The best part of that day, was that the nearby PC World store, which I visited shortly afterwards, told me that I could have the printer at the same price with no problems. They would have price matched without hesitation.
Another problem that I found, was Comets customer services. The printer developed a fault and Comet were totally indifferent to the problem. Eventually the printer manufacturer came to the rescue. As I said..Never Again.
