MWEB is pathetic and have ****** from my account

I requested an uncapped product from MWEB. They were supposed to have Telkom convert my line to receive broadband, almost 30 days later this still hasn't been done. Contract states that I will pay pro rata for the month when my account is active, account still not active but they have ****** money out of my bank account. Can someone advise if I can lay ******** charges against them for this? Be warned people, pathetic services. 20 calls and 2 call backs later, still have no internet.
