Bad service and neglecting customers

I have contract with vodacom it's router and a laptop I loss my sim card went in for a sim swap was charged I payed cash told sim is fine.then I got home need to use my latop is not working anymore went back to the store get told when sim swap was done something was not activated it was a hustle cause before even checking what is a problem was told about a fee.now the router can not connect there's three stores at my work place go to one store R200 another store press both buttons on the router will reset one i was asked if i bought the route and the laptop that specific store.don't know what to do now really.I'm not someone who buy things on contract this was my second one I'm shocked with level of service vodacom is providing once you to take contract with them you on your own.I'm so disappointed
