Commissioner of Oaths Remote Help

Can anyone help me find a Commissioner of Oaths who would be willing to sign and stamp a document sent via e-mail and then scan and e-mail it back to me?

Discovery Health is causing me problems with my Medical Aid. They need an affidavit that must be submitted by the end of today. They sent me an e-mail regarding this only last night. They want me to provide proof of my income. I sent them my bank statements but apparently this is not good enough. I am unemployed, suffering from severe depression and anxiety, I do not drive, have a license or have a vehicle. Getting anywhere to find someone to sign my affidavit is next to impossible. If I don't this, my medical aid contribution will increase from R1400 to R3500. I cannot afford this and might as well just cancel my medical aid.

Any help would be greatly appreciated.
