Pathetic service from FNB Private Wealth

Pathetic service from FNB Private Wealth. I app**** for home finance with FNB. Firstly they response with a less than favourable rate. The private banker then says that 'they will see what the other banks do before they improved their rate'?! We then receive a better rate last Friday and they still come back with a worse rate and after we query they need another day and a half to review their rate. THere is no relationship between personal and business banking as they still need feedback from business banking where my business account is help. What is the point of Private Banking if they a simple rate negotiation takes 3 days! FNB wealth is extremely efficient at marketing new products however simple service requests ends with really poor service.
