I have been using Aircel sim since 4 years now. And I thought they provide cheap data tariffs and call rates so bought it , but after 6 months , I felt , I shouldn’t have bought it. I noticed it that they activate their own plans and make me pay for it. , I had recharged for 50 but , after 1 day. I gets deducted to 20 , n finally next day , it reduced to zero , so I called customer care and spoke to them regarding it , I said I haven’t activated any plan so why am I losing money , and their reply was , there has been some plan activated , and I told them to Deactivate it. And again after 3 days , my money got deducted. So I had worst experience .
