Domino's Pizza — late pizza delivery & refund not done since 1 month - concern ref no - 8976412

Address:

Hyderabad, Andhra Pradesh, 500050

We ordered for pizza from dominos which was deliver 1.5 hours late & the delivery guy did not have any oregano also with him.
It was delivered from the hyderabad - madinaguda branch on 7th april'19 (Order no 274) (Concern ref no[protected]. Based on my feedback i got a call from dominos stating that they would refund me rs.300 since it was delayed from their end within 8-10 working days.
It has been almost 1 month & multiple times of follow up from my end to their customer care helpline for which the standard reply i get is... The branch will call me & then they will issue the refund.
This is not done from a big brand like dominos - extremely dissatified with the customer experience!!!
