Appalling customer service – online

On 7 March 2024 I purchased two rugs and a vase online and the rugs were R0.01 each and I wow must be my lucky day. I continued with my order and paid. Later that same day I received an email from Tim Sherwood the E-commerce manager stating that there was an error online and they will be cancelling my order. I responded and said please cancel everything in that case. No response. I followed up regarding my refund still no response. Today(12 March 2024) I receive an email that my order is out for delivery. Tim first cancelled my order and I requested a full refund. Firstly why is it the customer’s fault when their site displays incorrect prices? And secondly they don’t respond to emails. Appalling customer service.
