Idea Cellular — Activate booster plan without my confirmation

Address:

New Delhi, Delhi

Booster 175/-30D plan activated dated 4-Apr-16 on My idea no. [protected] without my confirmation. I mailed to idea customer for deactivate this service but idea's executive hold me till bill will generate on 15-Apr-16 & advise me to do not use data till date, I do as well as he told, mailed again on 16-apr-16, 18-apr-16 then asked me to process will completed till 23-apr.16 & waive off my charge, but in the night 23-apr.call me & refuse to refund this charge.

why advise me to do not use data & waive off charge 175/- on activation day 4-apr-16 . Idea customer executive confuse me every time. If they refused me
same day I used my data, So I want to Idea waive off charge & take your data...
