Western Union money transfer

Let's say I'm selling dollars for pesos at the blue dollar rate. Do I get the venta or compra rate?
 
When I try to fill out the online form I'm stumped at the phone number 54 (AR) (###) ##-#### and the postal code.
Postal code here is 4 digits. It says my number is incorrect.???.
That's why I've used Xoom for years. Thank God for Xoom.
But it's always good to have a plan "B".
I use a non-arg number..
I used Xoom for a few times, but the exchange rate on WU is so much better that it doesn't make sense to keep using Xoom...

Example:
for 200e on Xoom = 54.100 pesos
for 200e on WU = 57.300 pesos
and I would like to note down that I included the 3,90 transaction fee on WU, without the fee it would be 58.470 pesos

That's a gap of 3.200 pesos which is like 6% difference, in my opinion that's a lot..
