No Service or communication from Telkom

During Covid my Telkom Waya Waya line was disconnected by Telkom still with a positive balance with no notification to my mobile phone or e-mail or a courtesy call. i have had my numbe for about 15 years. I have made several fault calls and got a fault resolved through the app, Phoned in eventually only to be told today that the line was disconnected on the 6 April and I must call sales to re-instate. Spent nearly 2 hours on the phone to find this out. Then try calling sales - 45 minutes later of on-hold messages and still no answer.
