Sharekhan — not helping if registered number not working any day

Address:	712123
Website:	sharekhan

If any day I am not able to call from my registered number due to any unavoidable reasons they are not helping for buying & Selling the shares if it is very urgent also they are not helping.
If I cannot get help at the time when it required then what is the use to be with sharekhan. I can go with other agency.
Sharekhan has very good repo in market but this is very un expected with sharekhan.
