WiFi Problems

WiFi Router stop working on 2 laptops. Take laptop to Mimosa Mall Vodacom. Tell me to format laptop first for virusses, then router will work. I do it at great cost. Router have same problems. Beg them for weeks to fix router. They want to test it first, but won't give me a spare router while they test for weeks. Finally take it to Preller Vodacom. Test router. Say there's nothing wrong, but give me the wrong router back. Check settings on laptop. All perfect Router still gives many problems. E-mail them twice to contact me back about problem. Get zero response. I live outside Bloemfontein and am disabled - limited, painful mobility. Vodacom show no understanding. Meanwhile I have constant problems to connect to internet, my only contact to outside world in case of emergency. Please, help urgently. Have had only constant problems since I signed this contract with vodacom. At the end of my rope. At the point of ending the contract and try to find a better service provider.
