Cantabil — False promise to customer by store at ajmer(raj)

Hi,
5 days ago i went to cantabill, vaishali nagar, ajmer(raj) store to buy the clothes. I have shopping of more than Rs 10, 000 and they take a photograph o[censored]s with there store members. I took one jeans and one trouser and ask them to do alteration by themselves.They said that they will do aleration and fitting of the two items by themselves when i did the shopping but when today i went there to take my alter jeans back. They refuse there words and asked for the alteration charges they said they don't know when they tell us or behave that they even dont know us or seeing first time.
So i am very disagree with the cantabill and i face this thing first time in my life.
So i want to file a complaint regarding it so no other customer get the same thing.The owner and staff all are rude and so i want my refund or give again all my clothes to them because i dont want to buy anything from falso shop like this.
I hope you can do your action fast and look for the best
