Airtel — Cheated on My existing plan & changed to Higher plan while requesting the Broadband

Address:

Hulimavu, Bangalore

I requested Airtel to install Broadband with existing No. They contacted me & convinced me to go with One Airtel plan which include Post Pain Mobile No, DTH & Broadband. Then they cjanged my exiting mobile plan from 199 to 399(without tax) & Installed Airtel Xtream Box (Paid Rs. 1500). Then no one contacted me for Broadband Connection.
Actually i was requested for Broadband, but they increased my unwanted mobile plan & Xtreambox.
Airtel is handling trick/making fool us to increase their plans through such useless plans.
