Bad service Poor etiquette

I have been with Takealot since 2015 and ordered since 12/21 with no issues .I needed a fridge and browsed for the best option on Takealot, the fridge was to be delivered next day it arrived 3 days later and with an unnoticeable dent(I only noticed as I bend to wipe it and looked up ,so dissapointed).I wanted to keep it with assurance of the warranty but was advised to return .Did the same and they refused my return and refund stating as I used the fridge and may have been the one to damage it .I hope that your *********** staff be retrained as I returned the fridge the same day with proof of the dent and the delivery driver placed the fridge in my kitchen ,I ask you how and when could I have damaged the fridge
