Expat Properties — irresponsible / no correspondence

My customer id:c1351720.
I have made all the required payments in time. There has been several instances they sent emails saying that i have to pay penalty for no payments. After raising complaint they would revert back requesting to ignore the email. It has been more than 6 months they requested me to make payment for registration. Till now no registration is done nor do they reply to any of my email. Not a trustworthy company. I contemplating to raise a case aginst them.
