AVOID-ADVANCED-AV C.

I don't normally fill in these reviews, but felt compelled to ensure that other innocent purchasers were aware of the appauling practices of this company. AVOID LIKE THE PLAGUE!
I recently completed an on-line purchase for a Panasonic Blu-Ray recorder which showed 'delivery within 48hrs' on their website terms, and they happily took the money from my credit card. One week later I called them to ask where the item was, and they tell me they are 'awaiting stock from Panasonic'. After further probing, they tell me they should know if it is available in another few days, so I call them 2 days later and they tell me 'The item hasn't arrived from Panasonic', and that I can have an immediate refund.
However, 2 weeks on from this, and the refund isn't showing, there is no correspondence from them to confirm anything has been actioned, and when I try and get more information from them on the phone, I get excuses like 'the computer is down at the moment', or 'I'll have to speak to the manager to see what can be done' or a similar excuse. On further investigation, it appears this company formerly traded as 'av-addicts.co.uk' and if you Google them, there are many similar instances of customers not receiving goods even though their accounts have been debited.
I sent frequent emails to them to chase the refund, none of which were ever responded to, and no calls were ever returned with any updates. I suspect from this that they are quite professional at taking customers money for as long as possible without delivering any goods.
Since I bought the item on a credit card, the card company has been able to reimburse me, and they are now seeking the repayment from advanced-av.co.uk. Either way, it's hassle we could all do without and on-line companies should not be allowed to do business like this.
I also suspect that any of the positive reviews posted on these sites are bogus and most likely put there by advanced-av.co.uk themselves!
AVOID! AVOID! AVOID!
