Honestly grateful for IMDA having setup ADR channel for regular consumers to air genuine grievances with the Telco
SIMBA CSOs did try their best but they have a tough job tbh. Stuck between customers and typical sinkie management bureaucracy. Unfortunately, anything outside the SOP then gotta use the right escalation channels and to get the management's attention. That speaks volumes about their org's flexibility, but that can be said with other local companies/telcos as well.
Newer MVNOs like Zym are great and responsive, (they were nice enough to resume the porting process via FB msg, successfully ported in next day) but once they reach a certain scale, who knows really?
As consumer I just choose what's best for my needs right now.
