Device blacklisting

This five star rating is for a service champion who assisted me this afternoon. After 10 days of trying to blacklist a cellphone with 100 calls to MTN, only one person was patient enough to resolve and follow up on my query. Sharijoy Thamaha of Bonza network is indeed a Champion. With a bubbly personality and patience, she went beyond and above her duties to assist me, she is a star. I wish all Call Center Agents can be like her.
