Disgusting Service & rude staff

Standard bank decided that the type of credit card I had with them would no longer be available. they suspended the credit card without giving any prior notification so I only discovered this when my card kept being declined. I contacted the customer service centre and was advised that it was suspended as they were doing away with the my card credit card & I could sort it out with my branch. I went to the blue route branch today and no one was prepared to assist. I was told I needed to complete a new application and have a stack of documents before they could assist even though they have all my details on record and I currently had a credit card with them. I have been a customer for 24 years and I was treated like an idiot by the staff. When I expressed by disgust at their level of service and suggested maybe I should move all my accounts to another bank, I was told \that's fine
