Non-response and no assistance from Capfin

I've been trying to make a loan application with Capfin since Monday the 15th of January 2024 and they have been sending me from pillar to post with the debimandate I'm supposed to be receiving from them in order for the amount to be paid into my bank account. This morning I did my 7th application with them because somehow my application keeps expiring due to a debimandate I'm still not receiving. It's surprising that at the end of each call I'm told that if the USSD doesn't work, they have an option of approving the Mandate on my behalf but they are refusing to use that option and insist on the USSD which is clearly not working for me. Please note that I've completed and resubmitted 7 application since Monday and still nothing.
