Worst customer service ever!! Bunch of liars!

Ordered Sumatra garden furniture (£375) all went well with order, pain in the butt to assemble got to last bit the coffee table glass scratched! Rang the dreaded South African call centre who were very apologetic but that's all they were, both my husband & I struggled to understand what the girl was saying. They sent someone to inspect the scratch for Christ sake! Then Rather than just replace glass we had to take it all to bits and send the whole lot back.
Decided to try again & order different one Borneo £499. Got no email confirmation of order, went on line to check and was out for delivery next day. Rang Arrow XL to ask for estimated time slot to be told it had arrived at their depot damaged so it was sent back to asda. After making at least 10 calls today and being told every time they were very sorry and they understand, that my case would be escalated and would be called back within 2 hours I'm still waiting 10 hours later. So, I have no furniture, no refund and no communication! How the hell are you supposed to deal with idiots like this. There is absolutely no way if contacting anyone in this country to complain. SHAME ON YOU ASDA.  BE WARNED DO NOT TOUCH THEM WITH A BARGE POLE.
