Bad network

2 months back i reported issue with internet, connection, i was made aware there were issues, with cell towers, which vodacom consultant told me, i should cancel, my contract, instead of addressing the issue with towers, i was disappointed, vodacom is my favorite network, so i need to know, since well i am supposed, to cancel home internet, must i also move away from vodacom, since even on my number, i experiencing same issue of network, why is it difficult that you guys can't fix your cell towers, and the only option is me canceling my contract what kind of solution is that?
