Airtel — not getting service for last 10 days

My porting request was taken on 1/11/17 and i was assured by airtel person that i will get the service within 7working days but till now my connection not resumed. I have followed up with airtel person for the same. When i told them if i don't get the service then i will move to other service provider, for my surprise your company guy asked me why i am so eager for airtel service then. This kind of service is simply unprofessional and not acceptable. I never knew airtel will give such pathetic service. Please address my issue and groom your employees so that they can provide better service to the customer.
