Thats right. One bad experience means we'll all suffer the same!!!
Its a sad but real part of ANY company these days that OCCASIONALLY customers ( a very small %) will suffer bad service. I have on occasions and on other occasions, with the same companies, have received very good service.
"One of the items I had ordered was out of stock (lying salesgirl)"
I would like to point out that sometimes items can go out of stock in the manner you mentioned. Sometimes the database take a while to update and so it can show 4 in stock when there are none.
"9 minutes waiting to get through to the "customer services" dept. (surely indicating a large number of dissatisfied customers)" or could be low on staff or any other reason.
Basically you got a bad experience but 1000's of people a day will continue to get good service from them. Make a complaint yes, but you can't make statements like "The reason for this posting is to warn prospective Simply customers that they can expect to be misled by sales staff and receive cavalier treatment from the delivery people" unless you can prove it happens all the time....
Which it doesn't....
