Stationery room bad bad service

The worst service from this company you can ever get,i ordered my daughters stationery on the 14th dec wben school closed,paid the full amount for it almost r1000 and atill have not received it,they dont answer your calls or mails and when you whatsapp them they dont read it or it doesnt go through,i had to go buy the stationery at checkers and spend another 1000 which i did not have had to borrow money but my daughter needed the stuff as they were doing aseesments at school,can anyone tell me how do i get them in the hands its not only me thrre were 4 other kids in her school also waiting for there stuff,i asked for a refund of the money they took from me still waiting,i might need to go to the police to track them down with there number that i have,and they are legit as the school recommended them as one of the stationery suppliers.
