Bad customer service NoTCF

I took a contract in December 2019 and up to today I am not happy with the service I'm currently getting with Telkom, my line keeps on getting suspended every month after 3 days of them loading data, however I normally do a direct payment either at pick n pay or shoprite, but on the 29 of May 2020 a debit order of 947 went of on my account and the lines were still suspended until I called the call center which was not much of help, the line is suspended again I called the customer service again and I was told that my debit order was done through collections and it will take 7-10 working days for them to update on their system, to my surprise today s day 13 it hasn't updated, mind u every month they suspend the line which means I forfeit the Data and airtime I receive, I have since then requested that can I cancel the contract, I am being sent from pillar to post, Telkom doesn't know TCF and their consultants don't really know what they are doing I'm not happy at all, my contact is ***
