Customer service sucks

I had an uncapped lte contract that was due for upgrade and decided to upgrade to the uncapped adsl line which was installed and connected at the end of September and I had my lte contract canceled on the 3rd of October but the lte account had a credit of R500 on it which was not carried over to the new account and on top of that I was further debited an amount of R357. 57 on the 26th November which was also a bill for the lte account despite my adsl account having a credit of R2 000. I then called Telkom to find that my adsl account has been charged from August (before the installation was done) but consultant was able to help in reversing those charges but was unable to assist with the reversal of the R857. 57 credit on the canceled lte account so I was given a number to call but when I do call they keep giving me new numbers to call with no one able to assist me. I am tired of calling these numbers because I am not getting the help I need. I regret even upgrading to the adsl, I should have just canceled because all I'm getting is people wasting my time and not willing to assist me.
