Remitly called me again today to explain the problem we're having with them.
Apparently they changed aggregators (banking partners) in Argentina last July, to a company called Remitee, and it seems to be exclusive. Remitee has an ANNUAL transfer limit to Argentina of $2.000.000 pesos, which I surpassed in August and why I've not been able to use Remitly since.
Now $2.000.00 pesos is only $2,860 U.S +/-. at today's rate, essentially makes using Remitly worthless as a source of monthly living expenses. This I made clear to the person who called, who was sympathetic but was unable to offer any further solution.
Then an hour-long online chat ended a bit more optimistically, though I'm doubtful a solution will be forthcoming. My previous 9-minute transfers were done through a company called MMT, not Remitlee. Previously, the aggregator could by changed with a chat but not today. So Remitee might now be the only game in Remitlytown.
It's great to actually be able to talk to a knowledgeable person if & when problems arise. But if they can't find a solution, it's time to take our business elsewhere.
<sigh>
Who knows what's up with MoneyGram? The problem may be similar but they have no customer service so I don't even bother with them anymore.
