You are *******ly taking money out of my account

Dear MTN<br> My ongoing saga with your incompetence continues. <br> I am actually going to take you to the Ombudsman and perhaps sue you for *******ly taking money out of my account. <br> I am a pre-paid customer. I received no invoice and yet you have deducated R515 from my account. <br> I can assure you that I will not rest until this is resolved and I will name and shame you on every social media platform that I can until this is resolved. <br> What I want is somebody in a senior position from MTN customer service to contact ME, to resolve this.<br> If you care at all about your reputation and your business, you will take this seriously.
