Atrocious Service

I opened a platinum cheque account with FNB on the 19th of February 2016. I transferred money into this account upon receiving the card from the Parktown branch. The issue is that I don't have documents acceptable to verify my physical address, as a result FNB promised to send someone to my address for verification. Since the agreement was made about three weeks ago, FNB has not bothered to call me about the verification nor send someone to come and verify my address. I call FNB every week, and every week I find a new person who promises to rectify my problem and yet almost a month later my account is still frozen with my funds in it. Last week I called FNB again and I informed them that the company they send to come verify addresses was coming to my house last week Saturday to verify my address for my Discovery Card which is an FNB card. With that information still no verification was done for this account. I have no clue what to do now, I want the account but it seems like the staff at FNB could not be bothered, almost a month later. Frustrated to no end and helpless
