Dear Madam, Sir,
around two years ago I moved back to my home country and last month I sold my apartment in Amsterdam, where I have prepaid TV/internet with KPN. I applied several time via your online form for "Opzegging door emigratie" but till now no success. I uploaded several documents proving that I am not citizen of Netherland and I work abroad. I do not have proof of deregistration at Gemeente though but in this situation it looks like it is not possible to get it reasonably. Why do I have no response till now and why I have to still pay the abonement? It is also not possible to reach anyone on the phone from KPN. What are the option to reach anyone?
