Client support only deals with "usual and regular" enquiries.
I find Wise very easy to use and very reliable.
My only negative comment is that client support are not willing to do more than scratch the surface of an enquiry, if the enquiry is out of the ordinary.
I had trouble with a transfer that failed three times in two days. 3 people in support all suggested that I had created the transfer entries in the wrong order. My assertion that this was not the case found no better suggestions nor was any staff member willing to discuss it further.
When i gave up and looked into the situation myself I resolved the problem in minutes. It should not have been beyond support's capability.
