Moan moan moan, all you ever do is complain!

Recently I’ve had cause to be upset with a company that I get a service from. I’m not going to name names, but I am wondering what stance I should take. This company has managed to loose or not act on 4 letters. When they finally did process my request they managed to not only fail to use my new address but change it to a completely different and wrong address that I’ve never had or used. They did that 4 times too.

I have asked to make a complaint before, but was told the customer services line was busy, someone would call me back. Obviously they didn’t. It’s not that anyone has ever been anything but pleasant and helpful (sounding anyway) to me on the phone, it’s more that this has been going on for months.

I really wonder what I have to do to get myself heard. How and what must I do to finally get acceptable service?
