mp's have the fast track on getting things dome because organisations and companies are a bit scared when MP's get involved, in case things escalate and questions get asked on the house of commons. Whether your own MP could help you or not largely depends on if what you were asking them was reasonable. As an example, when i worked in NHS customer services, a person wrote to us asking why, if they had a chronic illnesss (from memory it was epiliepsy) couldn't they get free prescriptions like diabetics do. We sent her back the guidelines on who could get free prescriptions (hich didn't include her) So she got her MP involved. It made us laugh a lot because we had to write back to him pointing out that the eligibility for free prescriptions was set by the government, (ie his party in power), and if he wanted to change it, his party were perfectly at liberty to do so through the department of health (in nicer words than that obviously). So although he got involved (well, probably his office staff actually) the person didn't get any free prescriptions
