PATHETIC/APPALLING SERVICE

I've had an unstable (and virtually non-existent) ADSL line for 3 weeks now and although I've reported the matter to MWEB's technical department several times (on 17/09 for the first time), they've done absolutely nothing about it to date! In addition (and out of desperation), I've sent communications via e-mail to MWEB's Melinda Sauls and Jill Petersen (whom I'm told are more senior employees), however, they've done nothing about it either! It's impossible to work under these conditions and due to the fact that I run a business from home, I've lost a substantial amount of money/income since 15/09 which no one/business can currently afford to do, and in addition, is totally unacceptable!
