Down the drain woolies

I am utterly disgusted by the treatment I received from woolies,my mom's account has been overpaid since she hasn't received any statements from them.ive been trying to get the money back for the past 3 weeks, I spoke to numerous people and they keep dropping my calls.on the 26/7 the documents was send through to the finance dept,it would take 2 to 4 days...last week I phoned again,after 3 dropped calls,documents was forwarded again to the fin dept,and I'm still waiting for the money,it's been 7 days...utterly disgraceful
