Pathetic

I have changed banks and for some reason Netstar changed one car but not the other. Subsequently I have asked Netstar to cancel my accounts with them, as it is a service that i need to request to use, they can simply refuse it if i havent paid. Now it appear they dont want to cancel due to outstanding payment. Despite having sent numerous e-mails, no correspondence or calls other than sending bills. Now i get phoned by debt collectors. Well done Netstar, you have lost a client for life.
