Airtel — Poor customer care services

They have got the worst customer service. I recently lost my phone so i had to blck my sim. For that i called on 121. First of all their advertisements and dats pack offers are never ending. Then the option they gave to choose frm to contact them were so vague to clearly identify which option to cjoose for deactivating the sim. They should understand there are matters more serious than promoting their data packs and should provide easy and fast redressal of our grievances especially in cases like these. It literally wasted 1 hour of mine to simple search where to request for blocking sim and finally had to wait till morning to actually visit their service centre. Even there tge employees said to go 121 and get it blocked. But i refused because i didnt want to waste yet another hour on this. So please limit your advertisements on customer care and realise that there can be some serious matters.
