Disgusting service from Samsung South Africa / Samsung Online Shop l ZA

I bought a Samsung Galaxy A12 via the Samsung Online Shop and paid with my credit card on the 4th of July 2021. Upon going through some expert reviews it came to my knowledge that the purchased phone is not that good at photography and videography - the primary reason why I wanted a new phone. I then contacted Samsung via the email *** on the same day with an instruction to cancel the order. They responded on the 5th of July 2021 and told me to wait for further correspondence from them. Surprisingly, the next day a delivery was made by a courier guy which l turned down on the basis of order cancellation. I then notified the character behind the mail *** of the attempted delivery and that l did not take delivery for the same reasons. This Monday the 12th of July, l called their customer service and was told a response will be provided within 24-48 hours. That time has passed and there is still no word from them. I followed up today on email and last Friday as well without any feedback. Samsung, you are just a big name with no business morals and zero respect for your client's feelings towards your products. Never again will l buy or advise anyone to purchase your product. Your service is disgusting.
