Articleship registration

Hello Admin, I need your help .. Actually I filled my articleship registration form on 2nd Aug 2013.. However I received a mail after 2 months that there's problem in registration bcz of use of whitener & clash of office & college hours. So I filled afresh form no 103 & sent to ICAI. Even then I received a reminder letter to comply with. So I filled afresh form no 103 again & submitted it 'by hand' to colaba branch before a month with corrected timings. But they denied to give me any acknowledgement for it. Till date, I've not received my registration letter. What should I do? Please help me. I belong to WIRC.
