Vumatel s fading service!!!

When my intertnet problems started, I notified Gigawave, which summoned VUMATEL to investigate. The support arrived and test were run between my home setup and Gigawave. After Vumatel discovered my macaddress was changed et Gigawave, it was corrected, but then Vumatel suggested they put a new fibre receptor unit in st my place as well. So Vumatel support tested the replacement unit, which was working perfectly now, and the support guy suggested the proper installation would be completed the very next weekend. I phoned two weeks later, OH he forgot!, see you next Saturday! That was a Month ago. Installation is still not complete!
