SmartVoice a dumb choice.

After many telesales calls I was persuaded in october 2019 to cancel my copper landline and switch to SmartVoice. The D Link phone provded in was ok but had a fault from day one, a faulty microphone: when on speakerphone the receiving party hadsdifficulty hearing properly. Telkom do not provide an exchange facility for a new but faulty phone, instead one books it in at a Telkom branch and waits! This is shoddy service indeed. Why no exchange service?
