MTN agents dropping the ball

I'm highly dissatisfied with the service we received from MTN. My partner attempted to sign up for an uncapped data offer, but during the call with a sales agent, she had to abruptly end it due to being in the hospital for childbirth, yet she disclosed enough information before the call was cut off. Despite the agent's promise to call back, it's been six days without any follow-up. This situation is exacerbated by the fact that we've terminated our service with our previous ISP and are now purchasing expensive data, limiting our ability to enjoy services like Netflix as before. I urge MTN to prioritize training its agents to promptly return calls to clients, as this lapse in communication could impact their bottom line.
