Exhausted Employee

In all honesty, I do not have the slightest clue as how to even begin this review as im exhausted beyond all belief. I was employed by Ignition, working for Vodacom Saves. I had a problem on the last week of the month of June. I was unable to report to work due to a lack of funds. I called my line manager on Monday. Tuesday I was off, I called again on Wednesday to report that I would not be able to make it in. Thursday I again off. On Friday I was unable to communicate as I had no airtime and only calls are allowed. I couldn't call during the weekend as I had no airtime still. I was then deemed resigned. I was then not paid for the 3 weeks that I had worked. I have been trying to get ahold of HR as I am unable to get to the Ignition offices as I have no funds to get there. I sent emails, to no avail. I have a sickly father who I have to provide for. My rental obligation has not been made. We are currently under level 4 lockdown and I have a father who hasn't ate and is at risk of being evicted and will be homeless. I am not disputing that training funds will be deducted. I am fully aware of this. All im asking is that my balance be paid to me so that I can make payments were necessary as I will not be able to attend any DE or to appeal. I do not know what more I can do at this point. Im honestly shattered.
