Airtel — Incorrect billing - charging the cug numbers also saying parent account number is different!!

Hyderabad, Andhra Pradesh

I have 5 airtel postpaid cug connections given below which are from cno it services pvt ltd registered on my name (Praveen kumar vinukonda) .

From the 1st billing month statement, i have observed a huge difference in bill charges as my cug numbers are not being considered as free but being charged as usual airtel local number. This is for the reason that all 5 numbers are not on the same account number (This information was provided by your airtel customer executive) but while taking connections the company name and id was
Same for all connections. But, why are they not on one cug account number?

I did not expect this to happen from such a reputed service provider like airtel. I am very much embarrassed!

I request you to go through the details in all my bills and revert the money you have charged me for extra amount. I am deeply saddened because of this issue by airtel and demand an explanation.
If you are not going to address the issue, please be aware i am going to publicize this information on social media and also pursue for law - suit.

Note: i have raised many complaints against this issue but none of the csr executives were helpful and was providing me an incorrect information
