Airtel — regarding the price hike to buy a sim card with only two plans for post paid and prepaid

Address:

Mapusa, 403715

I am really upset with ur mapusa airtel branch which offers only 2 plans each on postpaid n prepaid.. Which is 498 n 799.. My daughter had bought one sim paying 250 n she was told that post paid charges per month would be 498.. Tell me how rates can be fixed... N plus prepaid also they don't have of a lesser rate.. Till date i'm using plan 199 on my airtel sim for so many years now.. I'm using g this sim from 2003.. I want a valid response to my complaint...
