Mukuru refusing to release funds.

I sent money to my son in south africa on the 19th of November. Mukuru is yet to release the funds today the 23rd. They first tell me I left out my son's middle name. Upon proving that I did not. They then tell me I sent a wrong passport copy. They then blame world remit. And have basically been tosing me from one end to the other. It has been 5 days and my son is yet to get these INSTANT funds. World remit have emailed them 3 times and mukuru have failed to respond to them or attend to this matter. My son sat in their office over 3 hours and still nothing has been resolved. We have been left to beg for our own money. Very poor service. Poor customer relations. And a whole lot of lies. Very angry and frustrated soon to be ex client.
