SUPERSONIC - RELEASE OF LINE

I HAVE RECENTLY TERMINATED MY SERVICES WITH SUPERSONIC. I HAD GIVEN THEM THE 30 DAYS NOTICE AND PAID THE CLAWBACK AS REQUIRED. I WAS TOLD THAT MY LINE WILL BE SUSPENDED AND RELAEASED ON THE 31/10/2021. MY LINE WAS SUSPENDED AT 22:00 ON THE 31/10/2021 BUT NOT RELEASED. I HAVE CALLED THEM 25 TIMES SINCED THE 01/11/2021 WITH NO RESULTS. THEY KEEP ESCALATING THE CALL AND I WAS EVEN **** TO THAT THE LINE WAS RELEASED. UPON CONTACTING VUMATEL, I WAS INFORMED THAT MY LINE HASN'T BEEN RELEASED. I AM STILL WAITING FOR ONE OF THE CALL CENTRE AGENTS TO CALL ME BACK SINCE THIS MORNING. THIS IS PATHETIC SERVICE. I WORK FROM HOME AND RELY HEAVILY ON INTERNET. MY NEW SERVICE PROVIDER IS UNABLE TO GET MY LINE UP AND RUNNING BECAUSE OF THIS DELAY.
