I called them my self and told them that i claimed once they say they will ask the administrator to ammend the policy and call me back i have been waiting for their call until now i called again was put on hold for 15 minutes lady said she is also checking with administrator. They deducting money from my account every month but now they dont want to pay and my car is at vw i dont have money to pay them as they already worked on it . And when vw lady called them again they say must pay they will re-embers me but i do not have any cash at the moment . Can someone sort this out urgently becos im going crazy now
