Airtel Data Card — Waiting for my replacement

I am using airtel dada card, which is given to me by my company Jungle Lodges & Reosrts Ltd.The data card number is [protected] . I got this card in Nov since i got i have been facing s problem that it gets disconnected in every 5 mins or so i have to take it out or else restart my laptop again. Since then i have been in touch with airtel consumer people like Ms, Simran, Mr.Ravi, Ms Meeta, Mr Kulwant and many more. At the start they said we will look into the matter and gave me a complaint number 19326153 and said they will be calling me back but they dint do so, Then i called them they gave me a service centre address i went there and got it checked he reinstalled another software which worked for half an hour there but after that again it gave me the same problem. Minewhile it was Dec and they realised that this problem cannot be resolved so they told methat they will replace it by USB but since then i am waiting for my replacement and dint get yet its end of Jan now.
my problem is not yet solved???? and i am not being able to use my corporate data card which is making my job so complicated.i told them that i will file a compliant in Consumer court and they simply said your wish.. i never expected it from Airtel.

All my office Airtel data cards are having same issue and need to replaced .
