MTN SUPERVISOR UNBELIVEABLY RUDE!!!!

This evening i call 173 customer service! I am on pay as you go and have been a customer for over 9 years now. I spoke to an agent to explain my problem with data that i have let go for very long!!! I purchase 2GB or 1GB and an additional 500mb before each month ends!! My enquiry was i was feeling ********** that my 1Gb was depleted in 10 days when MTN also gave me a giveback bundle for same value. The agent did not want to log my dispute. And called supervisor that i didnot request to speak to. His name is Justice and he amazingly surprised me with his rude greeting and attacked me immediately, in a bully voice and was very unapologetic. The list goes on but i had to drop the call as customer service was at an all time low in that call!! I am saaaaad and angry!! It might be really time to port out of this network. Im in awe!!!
