Clicks does not honour their word

I am still waiting for personal explanation from The owner of Clicks as to why she has gone back on her word to pay the outstanding amount on re-upholstery of my couches and chairs. I have voice notes from her saying the payment is approved and she will send me the POP. She is now saying i must follow up legally ? My supplier acted in good faith under assurance that clicks Would pay for the re-upholstery and she also acknowledged that they were at fault having sent two teams to try and clean. I have never been treated to such bad service but it the blatant disregard for the client that I find the most disturbing
