Panarottis Pizza Pasta Highveld Mall

We did IT work for Panarottis Pizza Witbank, Highveld Mall. They are refusing to pay my company because the owner did not know that they phoned us for IT help, the POST system was offline and customers could not pay for food accounts! we came out to help them on a Saturday and now they don't what to pay us. I did emailed them but they are ignoring any communication.

We are still waiting for payment since January 2021!
