Bad service at Nike Stikland

Bought R4000 worth of goods, however wanted to return 2 items today. Security guard treated me very badly & I then requested to speak to the Manager. He was unprofessional. There was a queu outside due to covid, but tills were open, however they didn't allow me to do credit without standing in line with everyone that were shopping. A few people actually told me they cant believe it. Won't support your store again wanted! Unhappy client!
