Bad Service from Debt Busters

Good Day Guys I have a horrible time with debt busters SA

I thought that going under debt review would ease my troubles and my financial stress. So I find debt busters info on clear score website and ask for assistance. The following people from debt busters assisted me..Mnr Max, Mnr Chad. We reached an agreement were a monthly premium of say +-R79000 would be deducted from my account. I signed the agreement. The third month a email landed stating that R9751 will be deducted from my account. I was not happy about this.. I planned my new budged on R7900 I ask them why the raise of almost R2000. They answered that on of my creditors was not happy about the proposed installment. Why did they let me signed an agreement in the first place. Why did they not first negotiate and then come with a full agreement to me. I then try to contact them,, do you know what they do...they just not available.. Im trying to cancel these blood suckers and cant even get a 17.w form from them..They putting my calls on hold and my dear airtime is flying. then the agent is not available. I wish a laywer can assist me to sui the living hell out of them.. Im feeling more stressed,, they are not kind to me.. they make me feel that im not client worthy....I just want the 17.w form that's all and they cant even do this...I already sent emails from the August imforming them that i do not require there service anymore. I noticed on there emails there are pictures of winning awards...How can a company like this, that are treating clients like dirt win awards.. Mnr Peter can you assist
