Airtel has changed my plan amount and also put a lot of international data charges. Though I had not used any of their services during while I was on international roaming. I was using the same number of international roaming for the last protected months and was paying a monthly bill amount of Rs protected. However, for the month of March-April, they had sent me a bill amount of Rs protected. They had changed my plan though I had not given any consent as my mobile number was switched off most of the time. Also, I had taken any service of mobile data while on international roaming. The only service I took was incoming messages and for that, I was paying a monthly bill of protected rs. I do not what changed suddenly on the part of Airtel for changing the plan and charging me such a huge amount.
