MTN store 86 Carnival Mall (Rudest Consultant in the history of consultants!!!!!)

What on earth!!!!!!! My phone was defective and when i called the agent at carnival mall he was the rudest person I have ever met in my life. He had the audacity to tell me that I am disturbing him without even hearing what i had to say. He thereafter blocked my number. This is disaapointing to say the least. I will never visit that store again
