BAD customer service !!!!!

I have a LTE contract that expires on 1 June 2020 from telkom. After numerous unprofessional telephonic communication with telkom service operators during lock down level 5 an 4 while stores closed.

I finally got thru to a Lady ,which I spoke too from 25/5/20 confirmed it will be cancelled an no money will be deducted from the 1 June 2020. Which did not transpire an R567 was removed an not R 513 with regards to this I was suppose to be reimbursed with the difference as per my reference below ..

She confirmed that my last payment was on the 30/5/20 . The lady on the phone also reminded me to not use any data an to call in again if the account is active. Which I did ...

I, then made two more calls an last communication was to a male Service consultant 14/6/20

I had not used not a single megabyte or gigabyte data since the 1 June 2020 an asked why the account still active an data still available . His manager was suppose to cancel the data an remove the account as per previous telephonic communication of enquiry.

I was very upset to find that I was billed R513.57 on the 1 July 2020 Now the 4 July I get another invoice for billing of debt order for the 30 July 2020 for R 315!! I have been numerous occasions to your Telkom store in blue route mall an the services been patethic ask to call the call center myself an numerous airtime I used majority time I only get through to someone 30 - 50 mins later of my own airtime .

Now I'm sitting with 1) I have a billing dispute for May 2020 that I have been charged more for an not as per invoiced. 2 ) Billed for services in June 2020 of the account that has not been cancelled , inactive an services that was not rended 3) A Telkom account expired May 2020 still not been cancelled !! 4) I have now been billed once again for July 2020 for inactive account

I need clarity on how to escalate this problem as this is unfair an ********* practises of services provided. If I stop the debt order this going to mess up my credit score on the credit bureau. I'm highly agitated, frustrated an need a resolution.
