WHAT ON EARTH IS WRONG WITH THE PHILIPPINES CALL CENTER? and why is T-Mobile fielding all calls out to them??

A big reason why I left my prior service provider straight talk, was because the call centers were outsourced to countries like the philippines and India; which made communicating effectively impossible. The headaches from deciphering other worldly accents and dealing with people who are not proficient in English is more than enough to justify a change of service. Especially as prices rise, the quality of service MUST rise with them, however that is not the case with T Mobile. When I first signed up in 2017-2018, T Mobiles most redeeming quality was the fact that I spoke to my fellow countrymen who were ecstatic to help me. Fast forward to 2025 and I cant even find the phone number for customer service after scouring the T Mobile app. Ironically enough, they make the live chat feature really easy to find and use! Anything to direct customers to T Mobiles AI customer service. My issue now is claiming a rebate that was offered from a TMHI promo. I signed up in October of 2024 and as of today 6 months later I still have yet to receive the promo. Had I known this would be the case, I would not have signed up for TMHI. Not only is there the rebate headache, but the speeds from TMHI are inconsistent, especially mid day. More often than not my speeds are capped at 10-60 MBPS. Mind you upon signing up the agents told me my area was getting high 300 MBPS and even higher. Which is does at times for periods lasting no longer than like 1 hour. I am not sure how server priority is determined but all of these frustrations have ruined my T Mobile experience and I will be looking to switching to a cell provider that does not outsource call centers, can make good on their promises and actually strives to take care of its customers in this greedy world run by corporate robber barons
