I have had endless problems communicating with this company since 21 September 2020 (yes 2020). Their telephone number advises that they are still working from home as per Government regulations!?! Having renewed without authorisation, billed through Telkom (which accounts were paid as we did not wish to have telecom services cut) they are now threatening "blacklisting" through Nu-Debt in spite of cancellation and double billing!!
