Poor service

I’ve been trying to complete my overdraft application for the last 2 weeks with no assistance been to the branch they claimed they can’t help as it was done online, I can not proceed online due to technical difficulties I can’t be assisted over the phone due to technical difficulties. Ive sent multiple emails and yet still no one has assisted me I was told I would be called back in 3 working days it’s been 2 weeks no assistance all I hear is difficulties
