No response from Schoolmall.co.za on stationery delays

We placed an order for our kids school stationery on www.schoolmall.co.za on the 5 Jan 25. We paid over R3000 for the stationery because we have 2 boys at the same school. Schoolmall was recommended through the school as this form was received when the kids got their reports. We thought it would be more convenient to order it through Schoolmall as the shops are full and lines are long during the festive season. Also, we have previously ordered through Schoolmall and got the stationery. I think that was a year or 2 ago. Schoolmall did however state that deliveries takes up to 10days from payment, and on their website its states that their might be a slight delay. However, it has been 10days already, when we try to phone then there's no one answer, and we even e-mailed twice and there was no reply. My sons had to be sent to school without the required stationery and we had to write a letter to the school as to why they dont have any stationery. I do not want to pay another R3000+, which will put a lost of over R6000. I'm really disappointed in this company and wish that they can atleast reply on an estimated date of delivery. At this stage it almost feel like we have been ****med due to the lack of communication from them.
