In my experience the worst are;
1.Payal. Leave you on hold for hours and wont answer emails that are in anyway complicated.
2.Dell. Complete morons, lost my order, i reordered, they canceled my order, they couldn't tell me way.
3.Currys. Local shop changed to Currys and now they keep sending me bills for something i paid for in the shop.
4.Sky. Make up reasons not to turn off your movies or whatever crap. I phoned up a couple of days later and the fella (must be the only intelligent member of staff) was able to do everything i asked their and then. Asked him why this couldn't be done 2 days ago, he couldn't answer that one, it wasn't even the end of my billing month.
5.Quinn Direct. Gave me a quote on a car i was think of buying. Just by chance i phone again to confirm quote, only to be told, we don't quote that type of car, the first quote was a mistake.
I seriously dread phoning any company if i have a problem, you just know its not going to be nice and easy and sorted out at the end of the call.
What your experiences?
