Misinformed about home wifi

I dont often complian but this time its becoming too much with vodacom false advertising and withhodlding important imformation

I recently find that home router is not uncapped after 3 years of having the contract and renewing it telephonically still not being told that its not uncapped and it can never be, and this information is new to me but no one is willing to assist without cost its very unfortunate to get such service while i have 3 contracts with vodacom, now i am stuck with a product thats does not work for me
