Upgrades without customer knowlegde

Good day people please assist in making this go viral so last year November 2021 our LTE wifi contract has come to and end with Telkom and prior to this contract ending in November of 2021 we received numerous calls about 5 or 6 from DSL(Telkom is there network provider) the company that signed us up back in 2019 to upgrade the contract and on all this calls we clearly stated we do not want any wifi service any longer once the contact ends in November of 2021 however they took it apon themselves to add a month to month subscription without our knowledge or permission this is how they try to manipulate people and get more money. People bear in mind we are still there customer as we have cellphone contracts which are still in contract and now they have suspended those lines as a result of this wifi and my wife's credit profile is also affected negatively because of this they refuse to remove the wifi charge on our bill and still want us to pay for phones we can't even use because they suspended the accounts bear in mind non of this was our fault to begin with yet we are held to this I won't rest until Telkom and DSL get what they deserve and we are compensated in every àspect that we have lost please assist in making this go viral I am sure there are more people victim to this.
