I tried closing my savings account with the customer service line...robots are picking up..I email..they requested documents and signatures from commissioners..yet when I opened it..all they needed was bank details...I then decided to drive 3 hours to a branch In cpt to close it in person...they guy told me it's sorted now I can wait for refund...A MONTH...AND STILL WAITING FOR REFUND !! Customer service keep sending emails again now asking more documents...nobody is explaining what the docs are for...I keep informing iv been to the branch to close it...gave reference....but they still telling me send pdf of the documents after I fill ND signed it...I then do so ..I send pdf they cnt open it...I send normal attachments they still can't open it..how the he&!^#^!!....I'm again 3 hours away from cpt working...so when do I get my refund? When is this going to be sorted ? What was the point of going to your branch if it's still not sorted...REFUND MY MONEY!!! AND CLOSE THIS ACCOUNT!!!
