Super bad service from Supersonic accont number S***

Account S-143151 cansellation. I am very disappointed in the service i have received from Supersonice from last year October as they fail to assist me when i have required serive from them.

On the 31st of May I sent an email to *** where I received an automatic response that my cancellation was received, but again no response. On the 13th of Junce I sent another email to *** where I acknowledged that I have settled my account and that the 30 days notice was given, again no response. Round about the 18th of June I received a phone call from Supersonic asking why I want to cancel? Now my problem is that on the 30th of June that fibre was ended and on the 2nd of July R2076,11 was deducted from my account even after I have cancelled and have settled my account. The cusotmer service I have received from Supersonic is non existent and very disappointing. I would like to see how you can assist me, on this matter. Regards Yvonne
