on the 14th of this month I started my new contract ( MagentaZuhause L ), as per the specifications and in the in the contract the seed should be 100Mbps (normal 83Mbps) for downloads and for uploads the speed should be 40 Mbps (normal 33 Mbps ). But the speed is only around 8 Mbps for both uploads and downloads. Why is this happening? and what is then difference in speed between  MagentaZuhause S / M / L if this is the speed i get for what I was promised and what I pay for?
