Terrible service

I'm working from home and I needed to buy a Monitor. I called the Makro call center before going into the store and they said I am able to buy the unit as it is part of essential services. I went to the Makro store in Cape gate and got the most terrible service from their electronics department. I asked for the unit and they told me I need an affidavit to purchase the unit. I said fine I understand but why didnt the contact center advise me of this to prevent me from standing in a long line here 1st and the guy by the name of Asad ( not sure if its his real name) told me that they dont want customers throwing tantrums when all I did was ask a question and pointed out a flaw in their system. I never yelled or screamed. I stood there completely flabbergasted by this man accusing me of throwing a tantrum when I was talking to him. I am disgusted by this store and their terrible service. Yes there is a pandemic but that does not mean your customer service gets tossed out the window. A simple 'I'm sorry mam we will forward the feedback to management' was needed but no he accused me of throwing a tantrum. What kind of people are you employing at your store?
