Airtel — change of package to an higher cost package

Address:

582101

I ordered an airtel dth connection online using their website only and i ordered a package which showed 301 sd channels and 33 hd channels on 1/5/2018. I got a phone call and i confirmed the said package. The local distributor came and installed the product on 2/5/18 and said it will be activated within half an hour and took rs 4100 and went. The activation was done and when i could not watch any hd channels, i contacted distributor and he said it will take at least 4 hrs for the hd channels to get acivated. I again phoned him next day as i could not watch hd channels, he said he will come next day as he is out of station. As i could not wait longer i contacted the customer care 4 times but they said the package is already locked and they cannot do anything. My original package costed me rs 230 and this package costs me rs 300 without any hd channels. So airtel dth has cheated me.
I want my original package.
