POOR CUSTOMER SERVICE AT MTN PAVILLION

My cellphone was ****** while on the 29th of July 2021. I blocked the SIM and went to MTN Pavilion shop on the 30th of July to do a SIM SWAP. I was assisted by Fazila, who assured me that my new SIM would be active within 24 - 48hours. My life is on hold because of my inactive line which is linked to my internet banking. I am disappointed with the poor service and lack of urgency with my problem
