Terrible Customer Service from consultant Nandi

Fin choice advised me that I have an account with Home choice which i never bought from them before, and Home choice advised me that they dont have me as a customer on they system, Called Fin choice back after 7x someone finally took my call, by then i was fuming with anger, the consultant couldn't help which i can not understand as they 1 company explained to her what Home choice said, but she tells me call Home choice, which i have done and told me i dnt have an account with them, she got rather ****y with me as i couldn't get any help from both companies that it ended up in a HUGE argument. Till now i have not received any call backs from them, including they Supervisor/Team leader Warren ???
