Would an apology suffice? you may want several outcomes at once, but if you know what you are looking for,you have a better chance of getting it.
2. KNOW WHERE YOU STAND
-Unless your complaint is minor it is worth knowing where you stand. You do not need to be a lawyer, but it helps to show you know your basic rights & entitlements and that you are familiar with any relevant code of practice or customer charter.
