Disappointing Service

I've signed up with Supersonic this week based on a referral. Sign up was quick. Router plus sim delivered 2 days later (also quick). Switched and was connected within 5 minutes which was impressive. After a few hours the problems started. Lost connectivity with connectivity since. Called the call centre and spoke to 4 agents with the last agent telling that my sim has been deactivated but the query has been logged with their back office technicians who will resolve and contact me within 24 hours. This has not happened which leads me to writing this complaint.

As a new customer I find the service very disappointing. One of the agents suggested I buy data as she is not sure how long it would take to resolve the problem (In response to me asking if I should buy data).

Please have my sim activated or resolve the problem with my connectivity if it's not a sim being deactivated problem.

Really hope Supersonic cares about complaints and contacts me on this.
