Paytm Mobile Solutions — negligence

Sir, this is ashvin from nagpur dainik bhaskar. I have lost my password. For getting new i have followed the instructions given by ur call centre machine. But when i click on link, the massege comes that the link has expired even before 10 minutes. Please solve my problem otherwise my trust on paytm will go to end. The balance with u doesn't matter for me, but i know trust matters a lot for any business firm. No ur customer care executive receive my call. What should i think.
