Vodacom please assist.

I am in arrears because the debit order was not released to vodacom although I had funds, then my number is suspended, when I try to make payment I cannot as my otp doesn't come through to my number obviously, I cannot go to a physical store to get my account upto date and the amount I cannot pay in full but I can pay an additional R1500 to bring the balance down. But vodacom cannot unlock my number in order to do so. Vodacom please assist me as I am awaiting for a job opportunity and the company will not be able to get through to me and how will I be able to keep my bill up to date without a job. TCF principles are out the door I guess?
