Many, many UK businesses just do not seem to understand customer service.
Last year, I bought some plans to build a boat from the USA. I emailed, received a reply within hours, was invoiced by paypal, paid and received the plans within a few days.
I then wanted to buy a basically home made book about how to build the boat. I emailed a woman in North Carolina who was selling the book.
Within 4 hours she replied that she was on her way to a 'vacation' in Louisiana and apologised that she would not be able to send the book for a week or so.
The book arrived in due course.
The lesson that Americans well know, if you want to sell something, the customer is King.
In the UK, as everywhere else, margins are thin and a business simply cannot afford to turn away trade, yet many do, they seem to consider customers a nuisance.
Over they years, I have had poor service from many companies.
All of them now bankrupt and gone.
