Airtel 3G Dongle — False Promise Regarding Internet Speeds

Address:

Delhi

Sir/Madam,

I have purchased Airtel 3G USB device(dongle) in october first week. They promise a speed of 7.2 mbps on the costlier 3G sim connection to be used with the USB device. In the month of october i got satisfactory speed of nearly 2 mbps which was sufficient for my job. But on the next recharge of the sim with the same 3G pack of Rs 650 / 5Gb , i found a drastic fall in the speed, and now the speed was just 20kbps. i have complained in the company many a times but there was no satisfactory response from their side and they were not able to give me the promised speed. This is a case of forgery/cheating.
My airtel device model is : E173Bn-1
Its IMEI number is : [protected]
S/N : 8CA4CA[protected]
My sim card number is : [protected]

Please ensure a proper justice for me.
Thank you
