Poor customer service

I was over billed by almost double my monthly subscription. It's now been a week and a half, 4 calls and 4 empty promises from managers and team leader.<br> <br> I have now been on hold for 20 minutes waiting for another manager.<br> <br> If a company can make a error on billing and rectify within 3 days ? <br> <br> Clueless to day the least, and also to be told as per t&c s it can take 40 working days for a refund!!!<br> <br> What a joke!<br> <br> Hopefully I'll get some higher management through this site.
