Unacceptable

Good day, Extremely upset with Vox. When I ask for my line to be moved to a new premises no told me it will be like a new line and that my contract will start new after Im with them for almost 3 years... The place I moved to was a rental and I was only going to be there for 6months so why would I request for a new contract/lnstall and not a move if I knew that they would do this. Now that I want to cancel the contract I must pay and exorbitant amount. They one of the agents call me and be rude speak to me like she want to, I asked for a manager to call me. The manager did contact me.. I reported the matter to the manager and she would follow up. The manager assist me and I explained that I wont be able to pay the outstanding amount all at once and would like to put an arrangement in place to pay it off. Everything was sorted now they come back and tell me that I must pay almost double the amount. I asked what it is for the lady tell me it for services that was on the account. I told her I cancelled the services on the portal that allows you to cancel it. She say that they didnt get it I should`ve send a cancellation email. This is after I spoke to the manager who put everything in place and I asked if that is the only amount I need to pay and that wont be other surprises.. she said thats all and nothing else. They really unprofessional and want to rip people off. I want the manager of the cancellation department to call me.
