Krungsri accounting - Western Union

[Dan SG]

Does anyone have any experience using the Western Union function on the Krungsri app to send money out of thailand?  Seems like a good / painless way of avoiding the inevitable blockages when you use other channels (I've tried a couple of times to send money out using UOB but it gets stuck at the head office).  I want to transfer about 200k every 6 months or so and the fees for using WU via krungsri aren't too prohibitive.  Source of funds is rental income on which i can demonstrate I paid tax (have a tax ID, filed returns etc); however UOB still have never let me, so exploring the krungsri route (i have an account open with them but use it less than my uob account).
