It was only a bit of light hearted ranting; I thought I might get some replies along the lines of "I know, you ought to try getting a builder/plumber/postal service to reply to emails left on their websites......"
I hadn't realised that even jokey threads in the Lounge are interpreted Very Seriously
As to that website on the link provided, it looks to be American and therefore of little to no use to me, as I'm in the UK (as shown).
Now I'll scuttle off and, er, await another serious enquiry to raise itself for discussion here.
ps. In reply to your question, yes, Amazon.co.uk are very responsive to emails from customers, as are most hotels. That reminds me (thanks!): must chase up an hotel in Germany wrt a booking in December......no reply since about August (you see what I mean? ? ? ? ? ? ? ? ? ?)
