Momentum website support service is very BAD

For the past 3 weeks I have been trying to login into the momentum website (Unit Trust) account. This one particular account is giving me problems I just cannot get in even with the 'forget username/password' tab. I have sent numerous emails to Dolly and the website team. Dolly has been trying to help but the website support team is useless, not replying to emails, saying its working but is not, they called me once and made a promise but nothing come of it. In my last email I have stated that I'm contemplating in closing my 3 accounts with Momentum, a customer of over 20 years. It's not Momentum but the people that's works there, but if support/service is bad then I will go else where with my money.
