Disconnection

I have been a customer for two months now with DSTV and my account get paid by debit order. After the first months 10 days after my debit order went of my account I was disconnected andi had to send my bank statements thru to Tumelo the Manager. I was reconnected for about a week and then disconnected again. In October they took both payments off for sept and Oct but I left it as I just thought I will be in advance which lasted about a week and got disconnected again took about 20 mails and about R400 to ********** before I was connected again and again had to send my bank statements. Yesterday got cut again phoned in very unhelpful lady who was going to get her manager to call me and I again emailed all my statements to both managers mention but to this second no one even bothered to email or phone me back. Please tell me what to do as I am a new customers with such bad service.
