Totally disappointed in Vox service

I've been a customer with vox for 2 years maybe little longer, for the past few months I've been literally begging them to sort out an issue with my connectivity and it seems to fall on deaf ears, I email and they couldn't be bothered getting back to me, you call and you run out of airtime before you speak to someone. This problem is endless but my monthly subscription has went up regardless of the fact that they are not delivering a service that I'm paying for. Whoever is reading this please do yourself a favour and try someone else and save yourself the time and headache.
