PATHETIC SERVICE- EVEN FOR COVID 19 TIMES

I am trying to help 2 people, who are due for an upgrade on their contracts, to get this done. I have tried calling Cell C on numerous occasions the past week en I am yet to be able to speak to somebody. I call the retentions department (at various times during the day), the automated voice note tells you their office hours are 8 - 5 but when you eventually get through it tells you you have reached them after hours???????? Have tried sending e-mails - a week later still not response. CAN SOMEBODY THERE PLEASE HELP AS THESE PEOPLE NEED NEW PHONES????
