Impossible to get any help

I tried to do a credit switch to get extra money in my account for a medical procedure for my mother. I was already pre-approved and went through the process until the very last step to just accept it, but I had to deal with a delivery so I locked my phone, now the application is lost and nobody seems to be able to help me just accept the quote I was offered.

I've tried calling but I just get sent back to the start of their call centre menu. I've tried going to the branch but all they could do was email the regional manager and several others but I've heard nothing back in nearly a week.

I know it's my fault for interrupting the process, but it should not be this difficult to just accept the quote that was finished and ready. This is so time critical and I'm really desperate for FNB to just help me, I tried to apply for this on the 22nd of February and have been calling and trying to get it sorted ever since.
