Hdfc preferred banking programme

Hi everyone
Myself Armaan and i'am new here
Recently I got offer from HDFC Bank to upgrade my account to preferred banking programme. Let's assume I have applied for it and I got upgraded and got all the benefits that It is providing which include higher debit card and credit cards and there will be no annual fee as long as I'm in that preferred banking programme. My query is that in case I failed to maintain AWB and got degraded will these cards also degraded? Or if not than do I have to pay there annual charges than? Which were not there in preferred banking programme
