IRP5 Request and HR Mobi Access Issue

I am a former FNB employee and need to obtain my IRP5 for the period I was employed at the bank.

I attempted to access it through the FNB HR Mobi platform but was unable to reset my password. The system encountered an error and sent a verification code to a phone number I no longer have access to. The platform also does not provide any contact details for reporting or resolving issues of this nature.

Please help!!
