HR nightmare

I am an ex employee of this company and needed assistance from their HR to assist me in claiming for UIF however i have not been assisted and have instead been sent from pillar to post the store at the eastrand mall branch cannot help and neither can their headoffice nobody answers their direct line and i cannot even leave a voicemail. As an ex employee and customer of this store. I feel this has tarnished the brand and what it represents. Is this the difference? They pride themselves in providing quality brands and customer service but i feel quiet the opposite and will close my account due to this bad experience.
