Useless business and service

I placed an order and the incorrect products were sent to me. This was on Friday 29/11/2024 at 11:30. I let them know via email immediately that there was an error and asked how to fix it. No response. 5pm that Friday I sent a message on their website with the same information and still no response. Sunday at 1pm I sent a message on WhatsApp and still have not had a response. It is currently 6pm on the Monday afterwards and I can see the person running the business is online on WhatsApp, but has refused to even read my message. Don't waste your time with this company, 24/7 service is an absolute lie and at this point the money back guarantee is going to be bull as well.
