No service from private clients

I was offered a private clients account last year in April. From the start I've had issues with late and no delivery. My card was couriered to me when I asked to collect at the branch. My credit card was NEVER delivered.(Yes up to now, please don't have it delivered, we need to discuss cancelling it.). I lost out on buying a vehicle using private to private because my banker didn't respond in time and ended up purchasing another vehicle financed at a much higher rate because I rather used a dealer's finance broker. I emailed Private clients a complaint with NO RESPONSE. Now on Monday 8 Feb 2016, I phoned my banker asking for assistance converting my homeloan to a one account. The consultant said someone would assist in 24 to 48 hours. I responded so I'll have a response by Thursday, the answer was YES. It's Friday. NO RESPONSE!!! I feel cheated by FNB for being offered excellent service at a higher price. I've been paying the higher price for almost a year, and I'm getting NO SERVICE!!!<br>
