The OP already stated that he can't email their customer support because he can't login.
However,the names of the founders and developers of bitcoinwallet.com are publicly available in the About page of the website(if you click on their bitcoinwallet pages). Perhaps OP can do a google search,find their social media profiles:Facebook,Instagram,Linkedin,Twitter and try to contact them by sending a DM on some of these social media websites.
Not having a support email address and being required to login,in order to ask customer support seems kinda shady to me.I would never use this bitcoinwallet.com wallet.
