No answer or e-mail to send queries

So I'm constantly having issues with the collections people in this unprofessional company. Almost every month I have to be the one to call requesting my balance as the e-mail address listed on Brabys doesn't work or is non-existent. I'm tired of wasting my airtime every month calling and the only thing I ever get is an automated text message to say thanks for my payment with no e-mail address to follow up with regards to my balance whatsoever. Its getting tiring and annoying that I have to constantly chase up for my account. Then it will be a case of I'll be paying even after the account is paid up and closed off and no one will inform me!!!
