Standard bank home loans division

The service I received from Standard bank home loans , particularly from Mongezi Nkasane is the worst service ever, I am highly disappointed and dissatisfied with the quality of service I received, i wanted to switch my home loan from FNB to Standard bank as my main bank is Standard bank so that all my accounts are with one bank, but after the poor service i received from him, I am not interested anymore I rather move my account somewhere else, he doesn't even have the decency to return a call or give an update. My application was approved, but he excluded the registration costs, all was needed was that amended,. For me to even learn about the approval I had to make follow up calls, during those calls not even once I managed to speak to him as I was always told that he is busy and he will call, not even once he called to give feedback. I had questions to ask about whether the application for the registration costs has been approved as he indicated in one of the emails that he was waiting for the credit department, from there he went quiet I sent him emails , left several messages for him which he never returned my calls until I gave up and my offer ended up expiring. The last I left was with Celeste who assured me that Mongezi will call me to give me an update, till the day Mongezi has not called,l. Standard bank has been recruiting me to have a private banker which I was considering taking, but after such a poor I am no longer interested, I am just curious to know why Mongezi felt I deserved that kind of service, as I believe his actions were intentional.
