Bad service from cell c

We have been trying since the 7th of April to get into contact with them to sort out the problem with our wifi. It's been disconnected since the 23rd of March and yet we still pay monthly for it. We need it for work purposes especially now during the lock down. We feel this is unacceptable. We had 1 call back and were told our case would be escalated to the technical support team. After another few mails sent and not getting through still no response since last week Thursday.
