Do not subscribe to Supersonic

I was happy with them, until I moved address. 27 October 2022, I moved without informing them, and the device stopped working. I was under the impression I will be able to cancel my subscription with immediate effect, because I was paying the bill in advance. When the device stopped working, I requested my subscription to be cancelled via the whatsapp portal. I requested it once on 27 Oct and received no feedback from my message, not even a hallo. I requested again on 1 November, just to be told I have contacted them out of working hours. A debit order went off on 8 Nov, and I contacted them again to cancel my subscription and they informed me they will escalate the matter and said I have to send an email to the address, which I did. By 15 November I haven't received notice that my email was received and I went looking for it and couldn't find it. I submitted it online. I called them on this day and they informed me that they have not received any request and also told me they will be deducting another subscription in Dec, to which I rep**** but why, the device is not working cause your techs aren't getting it sorted out. I called numerous times in Nov, trying to confirm if they received the cancellation, I have sent emails, I have been told managers will assist and they will not deduct in Dec, to my surprise, they did, and again in Jan and again in Feb, and all of a sudden they have changed the amount from R399, to more, then to R100, and in May they decided to change the amount to R50. I have received a statement in Dec, with R0 balance outstanding. I had to send the device back to them and pay R250 for the collection request. I requested a invoice for the R250 so I can pay it to them, I only received another invoice with a R0 balance. By Martch a different person send me an invoice with R250 outstanding. I paid the money and sent them the Proof. I don't have the device, I paid two months for services that I did not receive due to the techs on their side not getting the device to work and everytime they submit a debit order the bank will charge me R7 for insufficient fund. I do not have funds because I do not have work, and they keep taking what does not belong to them. I have received confirmation that my subscribtion was cancelled in Dec, with a case number. When I called in Jan, they said there are no notes on the system, when I gave them the case number, they changed their tune. The last statement I received was in Jan. In the meantime they keep submitting debit orders against my account, bouncing back and costing me R7 each time, money I do not have. I am sending emails requesting them to stop and asking for statements and they are just not responding. I do not know how long I will be taking this anymore, but thinking of moving forward and building a case against them, because they are forcing me to close my bank account, harassing me with debit orders and giving no care in the world for hardship of others. They are ********ly taking money from me and refusing to communicate or inform me on why they are taking this. I do not have their device anymore, they have received it back. I paid for services I did not receive, twice, and still they continue.
