I am an ex-employee of Converge ICT as of August.
I am sorry, but your 4000 pesos is gone. This is all done on purpose to raise funds for the expansion of the company (i assume, because we were actually by told NOT to process any refund requests and just pretend we are doing something about it. Sometimes we just hang up). They simply wont get back to you for this reason. As for pending installations, you can forget about it while the pandemic is going on as they will use that as an excuse even though there is no more lockdown.
Their tactic is to just ignore people who lost connection, ignore those requesting refunds. The endless ivrs and seemingly endless hold time are there for a reason, to get people to give up.
When i spoke out about how we are not treating the customers fairly, i was threatened to be fired. So i resigned.
