Is exactaweather.com Safe?

While exactaweather is a legitimate site they charge money for long range forecasts when the scientific methods they use are not proven and the forecasts are usually inaccurate. I purchased a "lifetime" subscription 2 years ago and though I am still alive, I no longer receive any of their long range forecasts but plenty of e-mails urging me to part with more money to receive a lifetime subscription which I already supposedly have. Have e-mailed the company but no reply. In view of the fact that I paid money for a product I don't receive, I view this site as a scam. Even if I did receive the product, the forecasts are not accurate enough to merit charging for them anyway. Therefore, don't be misled by the hype generated by this site or the quotes in national newspapers. They clearly need to be more honest and ethical in their approach if they want to be taken seriously.
