Worth less than one star. The company and their partners (so-called vertriebspartners) are dishonest and misleading. The moment you have signed a contract they stop caring and you will find it difficult to get out of their contracts. In my case I found an English speaking partner who explained the contract terms, but it turned out that none of it was true. At the same time I received weekly calls and letters with offers that I couldn't have anyway for a number of reasons. I strongly advise anyone to find another provider!
