Annoyed

So here I am again, almost feels pointless, I have been trying to solve my account with Telkom since 2016, I have paid my account as soon as I receive my Telkom bill every month on time without fail, I cancelled because of poor service and 2 years later decide to give Telkom yet another chance, only to find out that they have not solved a dispute I had with them Telkom handed my account over even though I owed nothing my account was cancelled in April 2016 and I paid the last bill in May, payment was received by Telkom and confirmed on the 08 January 2018 I call in to apply for the January big deal special only to find that it still has not been sorted. I have called in every week a couple of times to have this sorted eventually I escalated and guess what Telkom still wants money I don't owe, I don't get the special and I don't get Telkom be smart and doing the right thing my services were cut before June since I cancelled and made my last payment to Telkom yet I have a bill from August or October as there is confusion around that with the consultants. I cant understand as I was using a different service provider and the Telkom service was cut. If it is not too much to ask can this please be fixed I should have 0 on my account and I would love to qualify for the Jan deal which I called in for on the 08 Jan also I ran around getting details and information I had sent to Telkom and the company they handed me over to in 2016 a service Telkom had to render since i am the customer and the fault lies with you, i look forward to this issue being resolved soon
