Disgusting service

I bought a Skyworth 65" TV at Makro Crown Mines on Saturday 7 Aug 2021. In Sunday i saw the exact same TV at Pic n Pay for R1000 cheaper. I called the salesman immediately who said he would speak to hus manager and get back to me. Monday no response from salesman and pic n pay specual ends monday 9 aug 2021. He phones tuesday 10 aug 2021 abd informs me the manager says bo refund i can bring the tv back fir a refund. Absolutely disgusting. What would it beneifit me now as the special is over.
