Unhappy customer, bad service from woolworths

So i settled my woolworths loan on the 24 of June after calling in to get a settlement amount. Payment reflected on the 27th June. I called in on that same day to close the account. I had refund that was due to me. The consultant that was assisting me even cobfimed my bank account number for the refund. I have since been calling woolworths regarding this account because i haven't received my refund and the loan account is not closed. No one seems to want to help me they tell me different stories everyday. I am not happy about this service at all.. Im really disappointed infact.
