"No service but have to pay ?"

I have since ordered a landline phone in January of this year and to date, I have been allocated a landline number but no handset. I have on multiple accounts calling the sales, billing and technical departments trying to get my handset and as well as resolving my due account debt for a phone which I do not have.

I will not pay for a phone which was not installed as I have been billed for a service which is not even being used.

Please resolve this or I will cancel my order.
