Gross Nimble Group

I was given a settlement amount of R 445.86 for my Wonga loan and I had accepted a debicheck mandate for that amount for March 27 - I was able to settle it on March 15 but on March 27 they still took the R 445.86. I then queried that and they refunded me R 445.86 in late April. Yet they ae still harrassing me with emails telling me to settle this account - but on my Wonga profile, it shows I have paid up!!!!! Next step is the ombudsman!!!
