Vox Telecoms appalling service and attitude

I took out a contract with Vox and then progressed my own installation through them as they seemed very tardy. It took a week for their telephone department to contact Vumatel, the fibre company, I kept managing the tardy service and eventually an installer arrived. He could not compete his tests as Vumatel went down!!! I was told he had completed, which was *******. I then received an invoice for a full month on 26 Feb, 2 odd days afterwards. I had been told by Nikki the sales lady that I would be billed a month in arrears!!! I then started getting threats from accounts on SMS, Nikki told me that Accounts would contact me, which never happened, even my email to accounts BOUNCED! I paid the invoice under huge duress, and informed Nikki of the same. It is now over a week later and I have no internet or response from Nikki. Seems all Vox are interested in is getting customers and then sorry for you!! I am very unimpressed with their service and especially with their attitude, next step is to tell them goodbye and get a serious ISP.
