Telkom Pre-paid wi-fi "landline in PE not working for several days

Since 18 August 2020 my pre-paid Telkom wi-fi "landline" in Sunridge Park Port Elizabeth is no longer active. There is a signal, but when one wants to make a call the message "network busy" is displayed. Incoming calls are diverted to voice mail. On the screen the message "emergency call" is permanently displayed. I have tried to contact Telkom and have sent emails. No response. On the Telkom website they state that there are currently no problems is PE. Ha-ha
