HANDSET NOT WORKING ANYMORE

Took out a handset on contract with fonechoice a month and 2 weeks ago. The handset is giving me problems already I called fonechoice about a month a go and I was advised that the handset will be collected I am still waiting even today. I called them today to do a follow up and spoke to a lady by the name of Levern who advised me that she is not allowed to give me her surname I told her the story and she advised me that the couriers didn't collect the handset , when asked what the reason was she said they didn't attempt to collect the handset and I asked why wasn't I notified and she said its my responsibility to do a follow up not fonechoice . I told her that if its in that case I would like to cancel the handset because I cant be paying for a handset that is not even 2 months old but already giving problem she said that I wont be able to cancel it and that she will book for another collection. I want to cancel the contract and for the handset to be collect as I am not happy with the service I am getting from fonechoice
