"I have always said that we should be communicating more when we experience something we don't like. The important thing is to do it in a polite and calm manner"

Well said RLP
Its good advice for life in general too !

If only it was easy to 1)Voice your dissatisfaction 2)Keep things polite and calm
But you are spot on mate.

I just took my car to get serviced.
They ended up doing a major service
When I asked what specifically they did, the mechanic said ... "Oh a few things, including changing your break pads, changing air filter .."

Cost: $840

The funny thing is that the bill had two pages, all itemised. The first page said $410, which is what I read and what I thought I was going to pay
Then when I pulled out my card to put in the small EFTPOS machine, I saw the real total of $820

Like an idiot, I just pinned in my number, without complaining

$840
