Connection issue, tweeking of debit orders, cant get a hold of them

Telkom is a ****en **** show! I had a contract with them previously, it was so difficult for me to complete it because of the horrible service I recieved. Years later, I signed up again. The wifi has connection issues, it runs up 7 days within the month (even though I go to the office and only use it in the evenings), they increase the debit orders whenever they feel like it, I haven't received any statements since I signed up a few months ago. I can get a hold of them on email, telephone, the store can never help because they say the call center, yet you don't call the call center when you sign up. I just want them to cancel everything, so I can move to another provider. Ill pay penalties for whatever, just cancel everything. My goodness! its like only *********** people were purposely selected to work for this company. sies!
