Pag ganyan ang history mo, obvious naman na na may network issue sa area mo. I had the same experience pero with Smart. Sila mismo nag-suggest na i-terminate na lang yung account dahil wala na silang magagawa on their end.
Kung manghihingi ka naman ng bill dispute, make sure na well-documented yung mga reports mo sa Globe. May mga reference/report numbers ka ba sa mga naging tawag mo? I-list down mo lahat then i-present mo sa kanila as proof na may issue talaga sa internet connection mo. That way, mas madali nilang ma-track yung account mo at wala na silang excuse para sabihin na walang record sa system nila na hindi ka tumawag o nag-report man lang about the issue. You can also use the same reference/report numbers to terminate the account without paying whatever fees associated to lock-in periods.
With all of these network activity issue, yes you can ask for adjustment. But reporting this concern with the NTC? All I can say is Good Luck.
If you still have this problem about internet connection for the past month with or without network outage, Yes it would be better to terminate your line and ask for other network operators if they have a better network connection in your area.
But with regards to your termination fee, I think you are one of those postpaid subscriber who doesn't read the contract before you signed it. I don't think NTC can help you about your termination fees.
