Bad Communication and After Sales Service

Almost a week now with no assistance... Haven't even had the car for two months and the battery is completely dead. I have received no assistance from the sales agent other than I must email customer care. I email customer care, no response so I call to get told to email a quote for a new one which I did. I have let them know how urgent this matter is and every time I follow up I get the same response that they are waiting a response from the office. I got warned not to buy from WBC but went against the advice and now I am not even sure the Dekra report that is done is even trustworthy.
