Bad Bad Bad service

I have been using the same meter number for over 6 years and I have receipt's as proof of recharge on my account, my last recharge was on the 8th December 2020, yesterday I tried buying prepaid units on my account and the meter number was declined after sending several smses and voice messages with no reply my call finally picked by Ronnie who gave me reference number:*** and told me to return to the vendors and produce the SGC number and TI which I did this morning and still my meter is declining to recharge. I don't know what else to do as I am still waiting for their investigation on *** which was logged in July 2020. I now buy paraffin, fill my 2 gas cylinder and buy candles in bulk because I know that atleast once or twice each week I don't have electric, Just last week from the 27 December I went almost 4 days of no power my meat for December went off and no apology from them, What do I do with the references without being provided with a feedback or findings after investigation? Eskom needs to try caring for their paying customers ,I rate their service as poor.
