Order Confirmation # *** not reflecting on my profile

I ordered on 10.12 via the MRP Mobile app. I received the abovementioned order # and also received this via email. I paid by ABSA debit card. I checked my profile today as the order status hasnt changed and the delivery option is store2store which is 2-3working days. I logged in earlier today, could see the order # but the status had not changed. I tried calling the contact centre to no avail. I logged into my profile again, the order# has disappeared off my orders list. I called the callcentre, waited in Q, ONLY FOR THE LINE TO DIE. Called again, only for the same thing to happen. Logged a query on the MRP website via the lets chat functionality, no assistance. I need my order before this coming Friday, 15.12.17. The service &systems are absolutely terrible!False advertising if you ask me. Please can someone get back to me URGENTLY. Cell # ********** 311.
