Shocking service

I had a laptop through Fundi excellent service in the beginning and even after service but now that I need to take another contract out for my studying as my current laptop is not working, no one gets back to me. I call and sent emails to the same person and no acknowledgement nothing! I am hoping this will reach someone in Fundi who will be able to assist me as soon as possible please. No one knows how to even acknowledge an email or a courtesy call. Absolutely shocking customer service
