Appalling service and disregard for customers

On the 10/04/2018 I placed an order for a school project which was due on the 19 April 2018. Mr. Muhammed(one of the senior team member) promised during the phone conversation, that they will receive the order either on 12 or 13 April 2018. I will then be able to receive it on the 16th, latest 17 April. The order did not arrive and he tried to pin the blame on me, his explanation is that I should have sent an email indicating that the order was due on a particular date. He then a half-hearted gave an apology when he realised that I have a recorded conversation where he made that commitment claiming that the telephone conversations do not hold weight. He continuously asked me to understand their internal processes even as I offered to collect the goods from their warehouse, or for them to combine the project and deliver it complete to the school. I am advising everyone to be very wary of this company. I find them unprofessional, zero customer service, inflexible, internally focused on processes that do not help customers. I find no value in the company. Just appalling. My child and her friends got Zero their project.
