Horrible service from Investec

Unpleasantly surprised at how horrible the service and treatment at Investec has been. I recently moved from fnb after years of being with them. Upon my moving I really thought I was upgrading and would receive premium service. Instead, I have endured losing a house we had made an offer on because my account is seemingly not prioritised at all by Sasha and Dumisani, to add further insult to injury, my partner had considered also moving to Investec but after Dumisani and Sasha taking a whole 3 weeks without feedback to date on an application for refinancing of a paid up bond, he really does not want anything to do with the bank. We had approached a bond originator at the same time, who came with a response from Nedbank and fnb quickly, and even he has expressed shock at how horrible the service is at Investec
