Unprofessional customer service

I made an order on 4 February 2022 for a generator. Instant payment done. Delivery date 15 February 2022. On date of delivery I receive a call from Geoty letting me know that my product had not made it to courier, in fact is not even in stock. Was given a weak excuse about backlog. I called in again for more info on when the situation would be fixed and was given a run around. I have tried calling several times since and can not get hold of them. They are sitting with my money and I still don't have my generator. We have had multiple power cuts in the interim and suffered losses due to it. They should be held accountable for this. If I could I would give negative star rating
