WesternUnion were the pits. I remember sending money 20 years ago and having to phone WesternUnion and speak to operators who I couldn’t understand. Happy days huh 😂
I don’t know if they earn interest from money that is in transit but I doubt it. It’s usually at the receiving bank where the delays if any occurs, sometimes it’s bank holiday or their systems are down or the amount being transferred is subject to regulatory approval, but any money transfer company that repeatedly suffered delays for the reason would soon be out of business. I’ve used several companies in the past and for the combination of rate, speed and reliability then Wise is the best I’ve experienced. PayPal is instant usually but their exchange rate stinks
