Airtel — Converting STD numbers into ISD numbers and charging for consecutive months

Address:

Chennai, Tamil Nadu

For the past 7 months i have been using Airtel Postpaid CUG sim-[protected] taken from HCL Technologies where i am presently working. Each month i am made to pay some 300-400 rupees extra just because the system, as per the nodal and appelate authorities, is generating bills wherein i have send SMS to a specific number which, as per them, is an ISD one belonging to Bangladesh. on confirming with the respective user of the number as well as with authorities, that number belongs to West Bengal which stands to be STD. This made me to add a '0' before the 10 digit number but in the bill it is taking as '00' instead of one single '0' making it an ISD number. i raised the issue to the customer care a couple of times and also went upto the level of Nodal Authority and Appellate officer for southern region but instead i am getting blamed for the issue. I informed them i am not going to pay the bill for the month of April until and unless it is getting solved. FYI, for the month of April, i got a bill of 1173 out of which Rs. 620 is taken for that ISD issue. Request immediate assistance for this problem as it is persisting for quite a long time now and i am getting no help from the respective authorities from Airtel, which strangely is regarded as the country's biggest telecom operator. Thankyou!!
