Bad online service from Makro

I place an order on Saturday, today I got an email informing me that some items on my order has been canceled, no one called me before hand tell me that they are canceling. I have been trying to call them for 2 hours and they transfer me from one agent to the other and finally an agent gave me Makro Woodmead and again am being transferred from one agent to another. One of them said "am not the one who canceled your items so I can't help you ", mind you am using airtime here. I felt angry, disrespected and helpless..they canceled important items without telling me because it's their policy, even their WhatsApp platform is useless.
