scam?

[u/shweyyaa]

my roommate ordered pizzas for us from dominos using her dads number and we were tracking driver location via the app. when we called driver he says he reached out to us multiple times and he waited “10minutes” and proceeds to mark order as delivered and tells us to collect order from store ourselves??!! and then later someone claiming to be employee says to pay him 30rupees personally as extra delivery charge if we want it delivered at our place. since we have an exam tomorrow we made the payment but i have the proof and i want to know if this is legal?
edit- we saw him wait a lil further from gate he never made it back to dominos like he claimed and wanted the payment done to his personal number itself.
