No Response on application

I phoned the call centre on the 23/06/2015. The same day i filled the application form in and sended it back to a lady with whom i spoke to with this email adress [Email Removed] Again i phoned on the 30/06/2015 and still nobody can pick up my application. Is this the way to treat you customers. Or are we supposed to go to another company. They said they will phone my husband to finalize the application but no we don't receive any call? What are we supposed to do???
