They call around the clock. Leave no message. I actually called back.. this is a scam. Foreigner with broken English tries to sell you discounted auto repair.. you pay up front for discount to be used at a later date.
Same experience. They were rude and hung up on me when I started asking questions and told them to stop calling this number. Then they threatened to charge me with harassment when I complained about their associate and started to ask questions about their organization. I had to ask multiple times the name and location of their organization. On the 3rd call back they said Enterprise Financial Organization. They wouldn't tell me the name of their CEO and asked me why that would be important. Then hung up again.
