I am profoundly deaf and use BSL. Booked an appointment last week with the council to sort out a housing benefit issue. They cancel it because the interpreter's not available, so I go this morning.
When I turn up, the interpreter is not even an interpreter, but someone with a level 2 qualification who works there! Its like having an English speaker with a French gcse translating, it's understandable, but it doesn't flow and some words aren't quite translated correctly. Interpreters are expensive so clearly the council wanted to save costs somewhere 
When I get to the appointment, the man dealing with my case talks directly to the 'interpreter' and not me. The interpreter tells me about the claim etc, and when I ask to clarify something, she rolled her eyes and started again, not actually answering my point. This happened three or four times. The man and woman then started talking between themselves about what I was meant to do/should do (I can lip read) and when I asked was told 'never mind'.
They just treated me like they thought I was incapable of understanding even the most simplest of instructions, repeating things when I hadn't asked etc. I felt like a primary school child tbh.
IABU to not want to be treated like this and to expect a qualified interpreter?
