Very poor customer service.

I received delivery of my 5G sim with router combo for R999 on Friday 05/02/2021. after delivery the sim card was not activated I phoned customer support every day till date and they all come with the same story "I will escalate to my manger" "I will fill in a form" "I promise my manager will phone you back" I have even asked to speak to the mangers directly and then I get told "sorry they can not speak to me" I still to date 09/02/2021 have not received a single phone call or email to resolve my issue. why is there even a customer service line if they cant help you with something as small as sim activation? very poor service.
