Another unexpected deduction

The service has just been utterly disappointing the last few months! We had an issue with our alarm, a tech came out, replaced what needed to be replaced and tested the alarm. A month later our alarm went off in the early hours of the morning, and we waited almost 10 minutes for a call. My husband then called the call centre only to realise that the alarm was still on test mode since the day the technician came to fix and replace! So nobody picked up on this since the technician replaced the parts??? This placed us at ris****! For that call out and replacement of parts we paid over R2000. The following month I receive a bill for R700 - some or the other yearly fee. This month another deduction of R600 for some or other fee. How many fees do I still need to pay for this year? Every month it's not the amount I'm supposed to pay for! The accounts department is unfriendly, unhelpful with no turnaround time on assisting with any issues - I wont even bother calling to enquire this. Why not send your clients an email to with the expected service fees for the year and when it will occur. I'm just over blue security, I have spent serious money for the last 3 months which has just been painful! I just cant seem to budget correctly with these unknown amounts taken from my account without notice and the blatant disregard for our safety left in a technician and call centre agent's hands has left a sour taste in my mouth!
