HDFC Bank — Misguide and not issue Debit Card in Minor A/c

I have a minor a/c of my son in HDFC TONK road Jaipur (Rajasthan) Branch. I have the main problem they HDFC bank donot Issue By Debit card in minor a/c by the reason that they have no policy of that.

before it was final happened, i phoned personally to HDFC bank Branch Tonk road and try to contact branch Manager but he was not found and one of bank staff told that you should fill a a form and deposit it in your any bank branch,

I filled a form at Udaipur Branch and at udaipur branch also customer care excutive did not tell me that in minor a/c debit card cannot be issued, and accept that form and give me receipt of that form

After passing 20 days i again try to contact customer service and they told me that in minor a/c bank cannot issue debit card

if this is the rule why bank excecutive donot told that debit card facility is not availble in this a/c and final they waste my time and money also
