Supersonic - no refund even though paid twice

Unfortunately, Supersonic decided to suddenly take my funds by debit order after paying by EFT for a year. This resulted in myself paying one months subscription twice, once by EFT and once by debit order. I have comp**** with all instructions to try and get a refund, logged tickets, sent emails, sent proof of payments, could not use the wahtsapp communication number as it has not been working for some time, etc. Unfortunately, all of this has fallen on deaf ears and no after all this time I am certainly no closer to getting a refund.
