webafrica poor service to long time customer

i got a package from webafrica and when the contract expires the hardware becomes mine. So after having down time at least once a month and i complain and complain only last time i was having router issues and doing a firmware update fixed it, but i feel i was forced into it because i dont think i have had fibre for a full year so my router should have a warranty on it because its not a whole years old yet. I requested a router i wasnt not informed that i have to pay for the router because when i emailed webafrica i told them i need a router swapped out UNDER WARRANTY .. I get a router and almost 2 weeks later i get an invoice for the router. Not only am i being charged for a replacement which should be free under warranty exchange they charging me almost triple the price of what i can get it for from matrix computer or one of my friends at tplink. So now to avoid being charged the R999 i wanted to return the router, but now because i wasnt informed ill be paying before i got the router, i get told i got 20 days to return it .. why did it take over a week to send the invoice in the first place.. I got a courier to send it back to webafrica and i asked to be credited on my account for courrier services and i get an email back and i quote "Kindly note that Webafrica is not responsible for any 3rd party charges." what great customer service. ive pumped over R20 000 into this company over the passed almost 17 years and this is the great customer service i have to get .. ****** pathetic if you ask me
