Poor service of vodacom when u try canceling a contract yet still billed for a broken router

I purchased a wifi contract with vodacom from their freelancers Fibre department on 18 December 2024 however when it was delivered it never showed no internet connection we got in touch with the sales guy he told us to wait a few days we waited still no internet.We spoke to several customer care agent from vodacom yet no one could assist us mind you this was in the 14 day return policy coz by now we no longer interested, tried canceling they just say I'll put you through to Fibre department Eventually we were told to go to a vodacom store she then told us to come on this platform now we've been billed up until this day which is 21 February 2025 imagine
