cancelled month to month account exorbitant final bill

Telkom your customer service is absolutely appalling, after jumping through many hoops to figure out how to cancel my telkom account, i went into a telkom store and got the required info to cancel my month to month 10 meg adsl and phone line that i had from telkom, went through the online procedure to canceled my account online, few days later my internet went down and my phone went died on 20 July, got sms informing me that my account has been canceled, great stuff all is good and i am happy, i was very happy to pay for the whole month even though it was 10 days short cancelled without service i mean i thought that was reasonable,but don't cancel my account and then expect me to pay for another month without me actually using the service,rather cancel my account after 40 days and let me have the benefit of using my internet and phone then cancel the account that would be reasonable, so my final bill comes and its basically for 2 months so 40 days with out your services (10 days in july and the whole of august) and now you want me to pay for something which i cancelled and did not use this is total madness,this is akin to ******* or ******ion,i can understand if i had a contract with you but my account was on a month to month basis, phoned your call center numerous times to try and sort the issue out after waiting for long periods of time to speak to a agent all they do is come up with different stories log my complaint give me a reference number and tell me someone will investigate the issue and get back to me, well no one ever has gotten back to me, i am actually sooo very ecstatic that i have fiber now and that after this issue is sorted i shall never ever have to deal with you again telkom, it feels like i am beating my head against a brick wall over and over again total insanity!!! you could learn much from my current fiber provider's customer care an absolute pleasure to contact if you have any questions or problems,I have exhausted all other avenues i tried going through your proper channels to try and get this sorted but it seems like you just don't care about your customers so i have come here as a last resort, please i would just like this to be sorted out asap let me pay you what i realistically owe you and lets part ways telkom.
