OneCart unfair treatment

I’m forced to seek for help here because I’ve been **** to and ignored by One cart. I bought different orders today but my last order was not delivered but cancelled without a refund. I’ve spent more than R100 calling and talking to different customer service people but nothing has been done. Can they just deliver my order because it’s clear they can’t refund, also they fiddled with my OneCart App cause I’m now unable to do anything, I spoke to Ayanda and Michael
