I bought this heater about a month and a half ago. Since then it has only been used once or twice since it has been pretty warm for this time of year. Now it is getting cold and I really need it to work and all it does is blow cold air. Tried to call the customer service representative and have been told I need to buy these heat bulbs in order for it to work properly. I just bought it and it has only been used twice and now I need to spend more money on it?
