MTN staff employee hates their jobs

I am never seen such worst incompetence, rudeness, impatient customer service. MTN take priority in hiring staff that hates their jobs from customer agents to management no one I mean no one is willing to help, they are very good in transferring calls from one to another. It's been eight months since August 2023 now we in March 2024 still no one wants to help me. No one cares they just want to hang up and block my phone yet they owe me.

Mtn sold me a broken laptop and refused to change it when I told them it's not working, instead they wanted to fix. What the hell, who in the world would buy a second hand laptop at a price of a new one. On top of that they kept on billing me for five months for a laptop that was not working and I gave it back to them. Now they don't want to refund me.
