SUPPORT TEAM NOT HELPFULL NOR ATTENTIVE

Have been trying for 3 weeks to apply for a loan but the online application site needs to be updated or sorted out. Keeps giving the same error report. {Your Banking account number is invalid, please make sure that you have the correct account number. I have taken screen shots of the error message and numerously emailed support, but NO HELP was just advised that I need to use my computer not my phone browser and then my banking account number will be accepted and not rejected, well I have tried 7 different computers and still get the same error message and no reply from Support anymore. The Support team not very helpful nor friendly it's as if they are doing you a favor and you are disturbing them.
