Domino's Pizza — Service - delivery

Address:	Thrissur, Kerala, 680001
Website:	Dominos

Order no 79
Order date/time : 10/10/2016 08:37:07 pm
The order was delayed by over 25 minutes . on enquiry with the restaurant about the delay in the order, the staff very rudely hung on the call stating, " you pay rs 300 less". then i receive a call back from your staff giving me a class on the 30 minute guarantee policy .
After all this showdown the delivery boy ( john as stated by him ), makes a very very rude statement about my villa and murmurs outside of my gate as he leaves.

Please help me understand what this kind of service is called.
