Supersonic: Cancelation of Service & Non-Refund

I first wrote a review in an attempt to have my query and a refund due to me resolved on 5 Oct 2023. I noted at the time: “I’ve requested the cancelation of my subscription in March 2022. This was however never actioned by Supersonic, yet the data connection was seemingly cancelled, whilst the monthly debit order remained” and “I’ve also requested a copy of my contractual agreements for my perusal and again, no feedback has been received from 7 September 2023.” I received an immediate response the same day - “Kindly note that this will be escalated and dealt with”. I further receive email correspondence shortly thereafter, from a supersonic staff member, confirming: “I did manage to trace everything back and found that Supersonic did made a mistake, Supersonic did sent a sim card under your account to another client by mistake and that explains why there is usage under that sim card until end of June 2023.” “I am so sorry for this, and I am currently busy getting all the facts together to submit a credit note for the usage that we wrongfully invoiced you for”. Yet, there had been no further feedback nor refund received as per my records. I note none of MANY emails were responded to. I wrote a second complaint on 6 February 2024 (on hellopeter) and have not received ANY feedback nor response. I’ve further sent countless emails to various staff and departments and yet again, there has been NO feedback. Can I please request urgent intervention.
