Dishonesty

i have been complaining about my incorrectly billed account since i recieved a statement in December last year.<br> <br> i received a call from an incompitent consultant in early Feb, regarding my complaint, she couldn't help me and i asked her to get someone to assist me.<br> <br> 2 or 3 weeks ago, i got a call from a lady named Lulama from the accounts department, she called me to tell me that its all my fault and she sounded extremely condescending towards me continuously stating its my fault, because i set a cap on the debit orders going off my account.<br> <br> why would i set a cap on my account??? and how do i go about doing that???<br> <br> my account is billed every month for the service that receive.<br> <br> this morning i recieved an sms stating that my service is suspended regardless of me paying every month.<br> <br> why should i be held accountable for your mistakes????
