BAD SERVICES FROM MTN

I app**** for Sim data contract at MTN Woodmead on the 21 December 2019 with application number TV*** and my application was declined. I asked reasons for the decline and I was told that their Vetting Department says there is a possibility of ***** on my bank statement. I then asked what made them to conclude that there is a possibility of *****, what actions have they take to investigate their assumptions, i was told that they will ask the Vetting Department to respond to my queries as they don’t have answers and I cannot communicate directly with them. I was also advised to reapply while waiting for feedback which I did. Till today I have not received at feedback and to my own conclusion someone did not do their job and non of MTN management has done nothing to take action nor to explain my queries. Such a bad services from MTN
