Supersonic doesnt want to release my line

I have been speaking to these guys since Decmber 2021. i have beenon a prepaid month to month voucher that i buy I requested my line be cancelled on the11/12/2021. sent email to cancellations and received back from them. called back on the 8/01/2022 and 13/01/2022, i was told it takes one calender month, so the line will only be released at midnight 31/01/2022. i also updated my tellephone no and email adress with 4 different people. I called today 01/02/2022 to ask why the line still has not been released, as new ISp checked and the line is still not cleared. i have email from new ISP showing response from Vumatel that SUPERSONIC NEVER requested for them to be cancelled from my address. I have now been told By Supersonic that they will resend to cancellations and they will send me a email, but they still cannot tell me when the line will be released. This is absolutely pathetic. their cancellation email is automated response , so i cant send my emails to show what Vumatel said about no cancellation request coming from Supersonic. You cant speak to someone in cancellations, and the person you speak to at call center can only forward my complaint to cancellations. I have been sitting without internet for a month and a half. THEIR CUSTOMER SERVICE IS TRULY THE WORST EVER
