Waiting time to be assessed by medical services

Hi I was just wondering how long other people have been waiting to be assessed by medical services, Maximus. I am claiming ESA & have been doing for over a year, submitting fit notes from my GP. I have completed a ESA50 in June but still have not had any word about having a medical. I have contacted the DWP but they have given me the telephone number for Maximis. When I have rung tMaximus they have told me someone will be in touch.
My support worker had the same response. She has suggested I visit the local Citizens Advice or even contact my local MP. Help

I sent off my ESA50 in May and had my medical in June. I know someone else who sent his off in April and is still waiting to hear back.

I claimed in October 2013 and wasn't sent an ESA-50 form but have been called for assessment soon!
