Not willing to accommodate customers

So I bought a hair styling gadget from Clicks Liberty Promenade last week 26 April 2025, I misplaced or might have lost my slip and tried to return the item today 30 April 2025 asking them to trace and print a slip via my clicks clubcard and they , zintle, sharney and barbara advised that they cannot give me a cash refund as I do not have the original slip, this is however very strange as I bought something from clicks last year and they were able to trace the slip via my clubcard and give me a cash refund, but suddenly now they do not give cash refunds, I then requested to liaise with their head office and they called and put me through to Mishka, I asked to speak to a manager and I was told the manager is not available, well not surprising at all as managers are always not available to deal with customers, it's such a norm, I then raised my voice and told Mishka I do not want to speak to her but to the manager and she said I should not shout at her and then she dropped the call, how professional, I would like top management to contact me regarding this complaint and to discuss a way forward for my refund and if they still refuse to give me my cash back, I will take this matter to the consumer protection act and the ombudsman, so I am waiting for a call from senior management, I am contactable on *** or via email ***...I await an urgent response..
