Worst wifi provider ever

Unfreaking believable, I was debited this month for a service I canceled 2 months ago, I was told September there will be a debit for August as payments are postpaid. I was debited this month even though router was collected beginning of the month and I never used wifi after I canceled it and on Friday I was told my refund request was being escalated now today the call center I called told me I have to pay for September even though I canceled August..... I am today logging a complaint with ICASA, CPA AND NSPI
