SUPERSONIC(*******) - DONT WAST YOUR TIME WITH THIS PROVIDER!!

I had an lte line which i cancelled in January and upgraded to fibre, they now debit my account for the LTE from January plus the fibre line. I have tried numerous times to get hold of them and have the emails to prove cancellation and that they would fix this but nothing nobody calls you back you hold on forever and get cut off. I have had it with this **** company. i will cancel this service and stop the debit orders and go with a new service provider that is more competent. SUPERSONIC IS USELESS!!!
