Lack of response/feedback

Sometimes, I feel this is the only way to get some kind of response from these guys...

My monthly payback is being calculated on an incorrect premium amount. Someone needs to fix this or I end up getting less than what I'm supposed to. It's a simple matter - why is it taking so long for someone to resolve?

I sent an e-mail on Wednesday - no response I sent an e-mail on Thursday - no response Still no response by Friday!

Why then state that someone will be in contact within one working day???

Let's see how quickly someone pays attention now that this is in the public eye.
