Mass Solar: Website is a ****

I ordered a portable power station (518 Wh) from Mass Solar on the 3rd of April 2023. On 6 April 2023 there was a message in my inbox stating that my order has been cancelled and refunded. I have, however, not received any refund. I lost R4 899.99 to these people and I am very upset. Order No: MS811836FZ
