****** no answer from support of facebook

I requested a new simcard to as I have lost my card and I received it in June, I paid the R274 that I was owing on the 2nd of July 2020. To my surprise the simcard is not working. They send me another card and it is still not working, they are not answering my queries and their call centre number says the consultants are working form home.

I have sent several queries even on Facebook they dont reply. I am devastated as I paid my last cent to save on data, but it's all in vain.
