Can’t receive OTP (no IB access) due to being overseas.

The customer service is pathetic. I am currently in the United States, unable to receive an OTP to access my bank account. I have sent dozens of emails to SB, explaining my situation, asking if I can receive my OTP to acces my IB via email. I have had ZERO response in 2 weeks. I cannot access my bank account AT ALL. I need to access my account to make payments?!! Now I will fall behind on my credit card payment due to pathetic customer service. Do you just not care about customers, so much that you just ignore them? I even completed my forms for opening an Isle of Man account, but of course I’ve had ZERO response in about 5 months now. I’m sitting in America, great full being here, cause the people here actually DO THEIR JOB. Disappointment is a serious understatement.
