Supersonic Call Center Service is Terrible!

Call centre servcie is disgusting. Called on 05/10/21 at 11h05 to speak to somebody in finance as they keep on putting incorrect information on my invoices and I needed to add my VAT number. Had to wait for 20 minutes before I got put through to a consultant, who then tried to put me through to finance. Another 10 minutes later, they hung up!
