BIGGEST MISTAKE AND MONEY WASTING SERVICE

so after logging a call with hello peter i had 2 agents call me, the next day a technician came and put the router outside my house, he tested the connect on his laptop and the speeds where over 100mbps, he then left a few hours later i noticed that most devices could no longer pick up the coverage, me thinking ok maybe it needs some time to establish where is now stands, behind my dstv decoder, however nothing has changed. yes i have the speeds outside my house, i want to connect and have the speeds inside my house, my tv box which is 5g compatible and about 7 feet from the box outside has 2 bars connection ON BOTH FREQUENCIES, my playstation picks up about 82% coverage which is next to my tv box but keeps telling me there is a issue with your connection and cannot sign in which i now cannot use, my phone even standing directly under the device has 2 bars of signal ALSO ON BOTH FREQUENCIES. i called your call centre today and was told to buy extenders which will then require a splitter as well because i need more than 1, WHY must i get additional devices in order for me to use the device, your website promises Full HD (1080p) video streaming - NO I DONT GET THAT Unlimited HOME wifi - NO I DONT GET THAT. your router box cleary states "Highest experience ever strong signal everywhere outdoor and indoor", sorry to say but this is just getting pathetic and is wasting my time, there is no empathy with what your customers are going through
