Sharekhan — Account Closure and Payment issues

I had applied for the Account closure with the equity being transferred to other account with all forms dully filled in the first week of June with no appropriate responses. On June 18th the branch got in touch with me and thru email asking me to close the amount pending for Rs.2604.43, which I did the next day by online transfer. I was awaiting the next formalities for closing but was surprised on 28th June to receive another communication that additional 471.43 has to be paid, for which I had mentioned that earlier amount has been paid already and hence I cannot pay anything more. I had to sell off the equity which I had and unfortunately the amount of 471.43 has been deducted from the equity which was sold and balance transferred to me. I am as yet following up for closure which has not been done and plus I am asking for my 461.43 to be refunded. I have all the communications with me in email including the amount which was requested on 18th June.
