MRF Tyres — Dealership denied for complete service delivery

Address:

Mathura road ballabhgarh haryana

I bought mrf tyre tube for my Hyundai santro 13". As per service agreed dealerships supposed to provide labour who change replace the tube on same time however Balaji tyre denied to do same. Conveyed me to get same from outside, i asked to reduce the cost since no complete service being offered but they denied again and straight away said to don't do anything.
Pls accept my complaint for same delarship and issue a show cause reason because somehow I paid an amount of 50 rupees to get the tube replaced from outside which is anyhow extra cost to me
