I don't know what he did. But the usual process is you get an sms or email from Reliance Retail Limited (RRL) to pay for the order. The sales agent sends the payment link from their device after completion of KYC. After payment completed by customer, invoice download link is received instantly on sms and email.
If he has ordered AirFiber on your behalf, then only he can answer because what he did because it is not the regular process explained by Reliance.
Btw, no one visited you in-person to complete eKYC?
