Wow Momo Foods Pvt Ltd — Very bad staff not at all responding to the customers

Address:

Shop 11, Ground floor, Station Road, hussainganj, Lucknow, Uttar Pradesh

I visited "wow momo hussainganj" (Manager name- Ranveer Mishra) outlet and I told them my order and I wanted to redeem my coupon and they repeatedly told me to come tomorrow in the morning.
Next day when I came in the morning another staff member asked me to come after 4pm.
This is the kind of behaviour they're showing to the customers.
