Disgusted consumer

I went to Woolworths willowbridge to get hot cross buns today ,love their extra spicy hotcross buns and so does my mother,so I bought two packets one for her and one for me.Once I got to the till I was abit confused at the total but paid and straight afterwards checked the price of the hot cross buns and realized it was 27.99 immediately I went to the manager (guy dressed in a suit supervising the cashier and explained that I ddnt know it's this expensive and would like to return it.this was paid for with my debit card.The guy then told me they dnt do refunds on food becoz of the lockdown their headoffice does the refund and they working from home so they not allowed to refund me.This upset me how can they charge so much and den when I request a refund it's not allowed.I went to the tygervalley branch but by the time I got there they were closed already,i asked around and they told me they do refunds and that they no sure why the other branch ddnt help me.I am disgusted to be honest I am sitting with items I dnt want due to the price and this guy at ur shop has the nerve to tell me to keep the product till the lockdown is done and den bring it back ..this does not make any sense.I sitting in a situation with do I keep the items or risk going out during the lockdown again to a different branch use my petrol to return this item ....I will definitely not be going back to this branch again.
