Capfin personal loan nightmare

I app**** for a personal loan with Capfin, i started the application on the 26 August, then finalised it on the 30th August around 8am, i got an sms to say i need to approve a debi-check, i was almost on my banking app the whole day, there was no debicheck, i went to the ATM, there was no debicheck, then when i went back on my banking app around 13h30pm, it showed the debicheck expired, but i never even got it, i called Capfin, the consultants are very robotic, the other one said i should go to my back, which i did, my bank said Capfin has to resend another one, i called and spoke to a lady by the name of ayiswa or something, she was not helpful and was very rude, i told her is better if i cancel because i need the funds urgently, she said i can't do that, so they can't help me and i can't cancel it, what must i do?
