Worst Customer Experience from Karibaa.com

An order was placed with Karibaa.com for books (Order Number: ***). I received an email stating that my order had been acknowledged and I would be contacted within 48hours. This was on the 4th January 2023. It's now the 25th January 2023 and still no reply. I have emailed their support desk and am not able to get through on the number listed on the webpage. I am beginning to wonder if this company is legitimate as it's impossible to get hold of anyone. Surely, if there was a delay ordering my books, I should have received some notification and an explanation for this or advising me an estimated time for arrival of my books. Whilst they claim to be cheaper, the customer service is shocking. Had I known this, I would have placed my order with a more reliable online company to order my books and not had the hassle of waiting ages for a response or for my order to be fulfilled. I wonder if they will even honour my order. I am very dissatisfied and disappointed with this experience.
