Dear pathetic Luno, answer me!!

I deposited money into my Luno wallet for the first time, and accidently used the wrong reference for the receiver (Luno). I have emailed them multiple times all the documents they have requested to correct this mistake. It has been almost a week after I have correspondence days with them and they still haven't corrected neither won't respond to my emails anymore, nor give me a number to call. Absolutely pathetic customer care, it is tough financial times we live in, be careful if you want to invest through Luno!!
