No customer service from RMB Private Bank

RMB Private Bank: After upgrading my phone and going on holiday all internet apps and mobile apps had limited functionality because they are unverified. And no way to verify them. Four requests to RMB for assistance brought no customer service whatsoever. Tickets I log to help me resolve this are simply closed with an ironic message about "excellent service". Issue unresolved after 3 weeks and ZERO customer service.
