Cancelling my order

I'm highly disappointed with the service I'm receiving from VOX, when they sent me a quote they were literally in my mailbox every single day and now that I've taken the quote it's such a nightmare to get feedback. My order has been completed and a month later I'm still running after them to complete my order. they promise to call you back which they never do. they put you on hold for over 30minutes at your cost. I'm over this service end will be cancelling this order. I cannot be listening to ****py music for over 30minutes everyday at my own cost just to get service.
