Unauthorized Contract Renewal

Dear Telkom, This morning I discovered that my contract was renewed without my permission and knowledge. During last year a technician rocked up to my door saying that he is here to change us over from ADSL to LTE. No explanation, nothing. Later I found out that Telkom is phasing out ADSL and because we don't have fibre in our area yet, we forcefully had to convert to LTE. LTE is a huge frustration. With everybody in our household either working from home or attending classes online, this damn internet is slow (which in itself is an under-statement).

But back to my main concern, I want this new contract declared null and void. It is through no fault of and/or action by myself that the change-over occurred. WHY AM I THE ONE PAYING???
