keep having to replace my van battery , the last one I got from the AA so igot a guarantee , anyway 4 months later im out working and it wont start so call AA he says my pump is draining battery and there is nothing wrong with it so they wont replace it , I told him my system was profesionaly fitted by brodex and wasn't something I put together myself but they insist its the system and wont exchange the battery , fella said to leave van running whilst I work , which would cost me extra in petrol , would look unprofessional and where I live we have one or two tealeafs [ only one or two mind ] anyway the point of going with AA was for my warenty but I feel they have let me down a bit so what do I do now please gang
