POOR AND USELESS SERVICE

After a struggle and long wait, my fibre was FINALLY installed. I struggled with the network range. After numerous follow ups Vox tried selling me an extender. I accepted the quote within the timeframe and received a response after two weeks that the quote had lapsed. It seems a mikrotik was installed instead of a proper router so why should I pay extra for an extender??? How can I pick up my neighbours fibre but not even my own in my own house!! I logged a call for a technician who was supposed to come on 30/08/2023. Till date NO technician or any call has been received!! I have received nothing but POOR and USELESS service from you!! I have all the reference numbers but seems to be useless as it states resolved but I still have no response!!
