Vox Nightmare!

My business moved offices, so had to cancel my contract and start a new one. The actual telecoms service was good. but the delivery on the new contract has been disgusting. One error after the next, and also they have taken so long to do anything. from reviewing my old contract to quoting for the new one, and now our actual installation has been a total "mess" up. they don't call back, the management are completely untouchable. they only deal with immediate issues and just completely ignore you on any other issues that they don't want to deal with. the experience has been a total nightmare! it's been going on for months. I'm locked into a 3 year contract with them, and have to pay penalties for changing in the middle due to unforeseen circumstances. I just cannot get joy with these people. I'm trying to run a business and we haven't got phones yet, since Friday the first. they are "trying" to get our phones in by this Friday! Every minute of the day, I'm loosing money and having my business reputation damaged!
