Change of banking details and debit order.

These life insurance is certainly have messed me up. I requested a debit order date change together with my banking details to be changed on the 16th of May and Miway Life debited an incorrect bank account which I was charged bank charges of R18.00 plus R185 for insufficient funds. I haven't received my refund as it was their error of not changing my details as requested. I have been sent from pillar to post and given empty promises. It's now more than 7 weeks still waiting for my refund I hope my children won't have to go thru all this should something happen to me.
