No communication and worst customer service from Oh my cake!

The communication and service from Oh my cake! is really pathetic. On the 9th of July 2021, I ordered my son's birthday cake online to be delivered on the 22nd of July (the day of his birthday). I called the number provided and no answer sent WhatsApp messages at 13:40 on the 22 July still no response. I had a look at Oh my cake's social media platforms and see they are active two days ago. I kindly request my refund urgently as my son's birthday is over and there is no need for a cake. At this time we are facing SME's should strive for excellent service, it is a pity that this business is a mickey mouse. Please refund me.
