Dear sir,
I am a very old customer of subject Postpaid number. I was shocked to see my bill No. BM[protected] dated 12 mar 24, which showed and levied hefty International roaming charges for 7 days totalling Rs 5949.56, while matter of fact is that I had never visited any foreign country. I have taken up this complaint through various means as given out in the References.
It is reiterated that I have neither been to out of country nor had I opted for any roaming facility during the period 20 to 26 Feb 24 for which I have been given a hefty roaming bill. In fact, during this period I was on a bonafide government duty at Dharchula in Pithoragarh district which borders with Nepal. Throughput my stay at Dharchula was on the India side. I remember earlier too I had talked to your customer care number 121 about this anomaly. On 12 mar 24 I had also visited their store at Alpha sector Greater noida and put my complaint there too.

I was charged international roaming charges of Rs 649/- per day for the period 20 Feb to 26 Feb 24, when I had visited Dharchula which is in India. I had been raising this issue since 27 Feb 24 and my e mail dated 12 March 24 and subsequent calls at Customer care. It’s very frustrating that Airtel is not addressing my complaint and hell bent on extracting irrational and illegal heavy bill for services not applicable on me.
I approached the Appellate/Nodal authority of Airtel to look in to my genuine case and get me a corrected bill vide SR[protected] on 21 Mar 24, I got a reply that the issue shall be resolved by 24 mar 24, alas I did not get any response till date. However, I got notification of revised bill of Rs 2886.28 (No detailed bill provided by Airtel), which I presume consisted of reduced IR charges. I never agreed even this revised bill because I did not ask for ant IR nor I visited a foreign country. As 22 Mar 24 was the last date of bill, therefore I had to pay the heavy and illegal amount of Rs 2886.28 to airtel.
Kindly look in to the heavy handedness and negligent attitude of Airtel and get me refund of excessive amount charged from me.
