Edward Tells me I am not the only customer

I app**** for a limit increase on my card a week now. With no feedback. I called the call centre and spoke to Edward the guy with such bad attitude. I asked Edward was it is delay and he tells me that I am not the only customer. I find this rather offensive and he needs to speak to customers with respect. I want proper feedback on this consultants coaching process. It's totally not fair on me as a customer been told that I am not the only customer. Maybe if he had treated me like the only customer I would have been at ease.
