Booking.com no longer supports internet exployer browser

Hello I need some assistance and I thought perhaps someone else is experiencing the same issue as me.

Recently, Booking.com stopped supporting the Internet Exployer browser and I was unable to log onto the extranet on my Microsoft lumia mobile phone.  They told me to use Chrome however I cannot download Chrome on my phone as it is not android. I did found some other browsers that I could use but this has only lasted afew weeks and they have been blocked as well so now I cannot found any other browsers which has been very frustrating and time consuming. Does anyone know of a browser that I can use on my Microsoft Mumia phone that is compatible with Booking.com extranet? thank you for your assistance   


Microsoft stopped making phones so its not long term feasible.


Android based is the future and very low cost
