Zone Fitness - no care in the world

As the good citizen that I am, I phone Zone Fitness Kraaifontein to make payment arrangements. I am told the person handling these things are busy and I leave a message to have someone phone me back (this was about a month ago already). 2 days ago I make a phone call again as no one returned my call from a month ago and I have debt collectors phoning me (could have avoided debt collectors if they had the decency to return my call) and it is now 2 days later and still no one returned my call. I told the person if my call is not returned I will not make any payment until someone has the decency to return my calls. This is so pathetic - they are quick tp phone a person when accounts are overdue but when you try to make arrangements they just don't give a damn. Whose fault is it now that no payment has been made???
