Query: Don't buy TomTom product, their support sucks!

I bought this product to use with my HTC HD2 which already has TTN7 with Thailand map installed. The map in the dvd was for TTN6 so I downgraded my TTN7 to 6 but it wasn't compatible with the phone. Then I contacted [...] to solve this problem and it took several replies between me and them. In early replies, they told me to "contact the dvd seller" which seemed not making sense to me because this case was obviously about techincal. After several attempts asking them to give solution professionally, the last answer from them was to "contact phone dealer" claiming that they didn't sell TTN directly. If you're still follow me, this issue was cleary about technical but they tried to make this looked like selling issue.I'm really disappointed to TomTom, not by the product, but by their customer care. My recommendation is "Don't buy any product from TomTom" or you'd feel greatly disappointed if you have to contact them someday.
