Charged for an account that was canceled and confirmed to be canceled

Upon relocating to a new province I was advised by my landlord to take out a contract with an agent who dealt with vodacom as they were efficient and had good Fibre deals (to my later knowledge all other competitors have lower prices) . I proceeded to take a month to month Fibre contract for R600 from vodacom. I was given an LTE router with 100gigs and told that within the monthu Fibre would be connected as my lines were already installed in the apartment. Three months followed and a lot of back and forth and I eventually asked for my contract to be canceled in September without having Fibre Connected as I was paying for Fibre uncapped yet only received 100gigs each month of which I never used all 100gigs each month. At the end of October I was still debited yet I had no connection as of the first. When I contacted support I recieved an email stating that the debit was not in error as I claim as I canceled too late in September and was therefore canceled end of October however my point was that the line was not active and had no connection and when I called vodacom in the first week of October they confirmed my line being canceled so I do not see it acceptable that I should pay for a service I never received for the full month of October with them confirming this in the first week of the month. I am utterly dissapointed in their pathetic service.
