I know this is an old thread.. and I have most which include Worldremit.
They can be competitive on charges etc,.but There can be problems!
If you do bank to bank transfers.. as I have done this week. I sent on Friday night... and was aware of a two day "process" time before transfer to recipient. And was later told.. delays happen when its out of bank hours in Philippines ! Which apparently includes Saturday and Sunday! Accepting Monday as the new week... and assuming the Philippines agency had the funds available to them from Saturday and therefore opening time Monday..... its Wednesday today.. and still no transfer to the Phils bank. If this is typical then forward planning is needed!!
