I HATE SUPERSONIC!!!!!

I have an ongoing issue with Supersonic dated to May 2021. they have doubled debits my account, they have refunded me and they have been inconsistent with they debits from my account. for the past two month they have not debited my account and I have called in querying this and get told, Supersonic will look into this and get back to you. as yet, nothing, now I have to pay a bill of almost R3,000.00 at the end of December, due to no fault of my own, but the incompetence of project management and the billing department. Again, I called in yesterday and spoke to an agent by the name of Masha, who when I asked to speak to a manager, her reply was "I am working from home" ***?? I then questioned her on how do I escalate to speak to a manager and she then muted me - then I called in again, noting I have to buy airtime to call Supersonic and wait 5 minutes to be assisted every time. I then spoke to Tebogo whom also could not transfer me to a manager. she opted to as usual create a call back as she could not provide me with a managers email address or contact number. as yet the nominated manager Rayno Ciluk has failed to contact me until now. I am utterly disgusted with this ISP and feel they have no rules and they can do as they please without any regard for their clients and without any repercussions. it begs raises the question if the ISPA is aware their incompetency and that they do not communicate with clients unless they want money and they do not address complaints. this is my third post on Hello Peter and still no feedback or communication on my issues. It feels pointless complaining and escalating your issues as their is no feedback!!!! I should never have signed up with this Company and what even more disappointing is that MTN probably doesn't care about their poor service either, but yet they Supersonic is "Brightened by MTN". Supersonic is Pathetic!!! Please don`t ever sign up with them.
