Apparently no network 15 minutes before closing

I walked into MTN in Killarney yesterday afternoon at 15:45 because I had issues with my service and the call centre advised me to go to the store for assistance. On arrival, all the staff were just relaxing (the gentlemen who helped me gladly pointed this out), arguing that their network is down. That was nonsense, he did not want to help me because he was closing soon and my problem (as a paying customer of MTN) was too much of an effort for him to solve on this Sunday afternoon.<br> <br> Can MTN verify that there was a network failure in that store? I doubt it.
