poor customer service

I went to foschine in Menlyn to apply for a limit increase I supp**** all the required documents, i was informed that an sms will be sent through if there are still any outstanding documents. Three weeks went by without hearing anything or getting any sms as I was told. So I went back to the store to enquire, then I was told that I wrote a wrong number on the application form and that I have to fill in another form. I am disappointed, why didn't anyone call or sms me to tell me that there was something wrong, why did I have to go back to the store to be notified of that.don't they do follow up. Talk about poor customer service.
