Poor service

Poor service I received so far from the NCR. I logged a query or complaint in the begining of July laready a month has passed with no resolution from them nor responses I called to follow-up more than 5 times every single time the person who answers the [hone says they are escalting & will recieve a call by the end of the day I am still waiting. I still have not received my refund from Evericious Ma***a who owns Credix and NCR is not helping at all.
