Intercare don't want us to pay amount owing

Intercare Accounts refused to send me a statement, as I am not the main member, while my husband is at a specialist doctor all day, and not able to send me anything. All I wanted to do is pay the account electronically, requesting the statement on my email address, but was told that they wouldn't. Don't you want to get paid? Then I get more threatening sms's. I don't want to deal with Intercare again. Will find another doctor elsewhere!!!
