Making the beach at Magaluf safer and cleaner

Dear Sir, At the east end of Magaluf beach there are some dangerous steps leading to two concrete bathing platforms. This pathway is strewn with old lilos, .bottles and other rubbish. Whose responsibility is it, Calvia Municipality or the Costas? Or does it fall between two stools? Come on Magaluf, make.the whole of your beach safe and clean. Yours sincerely, Robin Musters
