MRP are ********* ********s

It's been over a week since MRP promised to resolve my missing phone that I ordered online with them. I've been emailed by their customer support agents Busisiwe Ndebele, Slindile Mdunge, and Clancy asking for my phone number to call me which I shared with them but they never called. Every second day there's someone different which I have to repeat myself to. They don't bother with follow-ups to let me know how their investigation is going on how it came about that I don't receive my order which was supposed to have been delivered by Fastway last week on 2 Sep. If I don't email them first they stay silent. My account statement reflects the amount of the phone which means I have to pay for something I never received. I'm so disappointed in them as I've been a loyal customer of the MRP group for years now and after this experience I will surely be closing my account with them.
