I have registered for CA Final long back. As per Our Institute regulations I have revalidated by registration no by paying an amount of Rs 500/-. I have received a receipt from Institute acknowledging receipt of Rs 500/-. But till now I have not received any revalidation letter. Hence I have written letters two times to institute regarding non receving of revalidation letter. And after waiting for considerable time, I have posted a query regarding this in E-sahayaata and they confirmed that my account is revalidated from 01.08.2014 but they not sent any revalidation letter. Now I want to know whether revalidation letter is compulsory or confirmation received in E-sahayaata will be sufficient. please clarify
