Bad service

I have purchased a fridge online on 17 December 2025. I canceled the item on 18 December telephonically, however this was never escalated to the relevant department and the item was delivered on 18 December. I have made contact via email and telephone since then on a daily basis, however still no feedback have been provided as to when the item will be collected. I have spoken to a team leader on 31 December, who requested pictures of the fridge, which was sent on 22 December as well. I have followed up again as I still have no feedback. Contact was made via WhatsApp where I was assured this will be dealt with within 24-48 hours. I am extremely dissatisfied with the service received from all departments involved with my cancellation request as I am just not getting any feedback from anyone. Two additional emails were sent today without any acknowledgement or feedback.
