Vodacom Fibre

I did an installation with vodacom fibre ,and i can never pick up signal, i contacted vodacom and was advised to buy a 6/7 cat cord after purchasing that an agent told me he will assist in setting up the second router only that never happened because i need to pay for a second installation and another router no one cam help and i am now mentally frustrated , my contract is coming to an end so i must else go with another service provider
