"Wireless" internet does not work with repeated faulty hardware

Alcatel router with uncapped wireless router not working. Router is 1 month old, have been in for repairs, after 10 days the unit was replaced, and we received a 'new' router which does exactly the same as the previous router. Biggest nonsense after being to Vodacom repairs twice already and now need to go and stand in line for a third time so that Vodacom can send the router to Jhb to be tested and be without internet for longer than what we have had internet and having to pay for this service all the time. "Wireless" internet is such a meh, rather get fiber
