Worst customer service EVER - Should have minus stars for this company!

This company has NO CUSTOMER SERVICE at all. They do not listen to you when you go into their branch and then have the audacity to tell you it's a misunderstanding. There is no way to get hold of their HO and raise the complain with them. They just refer you back to the branch. I do not want to speak to the branch as this was the 2nd time that they are unwilling to assist the customer.
