No internet connection. bad service

7 days without internet connection. When we call the call centre number ***they put us on hold for more than an hour. I spend more R50 of airtime just so I could speak to one of the agents and sometimes airtime finishes before I reach the agent. Just renewed my voucher but still I do not have internet connection. The country is still on lockdown and I'm working from home but it's been difficult to carry out my duties because of no connection. This has given me a bad record to my employer as I always have internet access issues. Vumatel and supersonic are ridiculous.
