taxify application not loading on my cellphone since Monday 27th of July

Good afternoon,

I need to get taxify or Bolt application to be loaded on my cellphone ***. It stopped working on my cellphone.

When I try to install the BOLT TAXIFY APPLICATION ? it does not load. I rely on Taxify to transport me.

Please advise who can assist me to install the taxify bolt application on my cellphone.

Thanks Lydia ***
