@gowin Exactly.
Years ago, with my prepaid SIM, that was their explanation why they can't fix the issue with my number. Slowly, ₱1 or ₱0.50 is deducted from my load.
They claimed I subscribed to their promos, so they asked me to load up and they'll unsub me. Their agent was confused because he saw for himself I was telling the truth that I never subbed to any of their promos.
Called their engineer, they searched for my number, and the final explanation was that: my number is in their old database that they cannot search. I should change number instead and they'll deactivate my current number since it's old.
Like. No.
I had no idea then it was a real explanation and not an excuse.
