Supersonic are ******!

Pathetic service received from Supersonic. They are running a promotion where you get your first month free, however, they billed me literally days after signing up. I've been opening tickets online to query this as well as calling them and communicating via whatsapp since 03 January. A consultant informed me that they've logged a ticket to credit the invoice because I'm only supposed to pay from February. They have now suspended my services and all I get told is that my tickets have been escalated to the relevant department. They can't give me a turnaround time on how long this issue will take to resolve either. It's been 2 weeks now. Seriously, how long does it take? What a bunch of ******!
