Woolworths Poor Service

I had a personal loan with Woolworths, after I had paid the loan in full ( 14 days ago) I recieve a sms message reminding me there will be an installment deducted from my account. So I phone them to clarify the details. After I spoke to the lady she put me on hold for 8mins when I decided to end the call and to see if they will call me back. I soon release this will not happen. Poor service to say the least.
