No chance, You can call hundeerdtimes on the servicenumber and there is always another person who promise you, that who will help you, but there is no more returncall. Same with mails, lays the same letter of your question. An even when they promise you to get your refund, like in my case, they will not do it if its a high amount. The will find new reason that they must not pay. I had waited. For 6 month in the trust the give me a refund, but after 6 month the send back the the defect phone which had costed 5900 pesos.
