Telkom LTE contract for R429 per month

I signed a Telkom Mix LTE \Summer of Wow"Smart Home contract for R 429.00 only in a Telkom store.<br> Telkom is only allowed to debit order my account for R 429 per month but incorrectly bill me every month for an additional R 52.71 as they are charging me extra for the hardware - which is not what was advertised or what was signed for (I have kept the adverti*****ts as proof).<br> <br> I have been disputing this error and breach of contract since the beginning of January and I have phoned numerous times"
