Disgusted client by inspire (Lewis group)

Here I am again with an extremely heavy heart. I took an account with inspire (Lewis) and took bed linen. Guess what, I have yet learnt a lesson. The agreement was for 6 months however, i am now getting calls and texts that my outstanding balance is R1328.31. What is it for? I asked. No one was able to give a direct answer. One person calls in and says one thing and the next person calls and tells me something else. The last call i received i was told my last payment would be R350 cash payment ut to my surprise i received a text saying I owe over a thousand rand. Am I paying for previous clients who fled without paying their accounts or what? Am I settling other people's debts here? What exactly os going on? People from the Finance team or collections team called me several times but still they had no concrete answer to the questions I asked them. Next thing you know i will be blacklisted for not paying my account and yet they are the ones who have no clue what they are doing. Guys, get your act together, sort this out and contact me when you all know what you're talking about as I am not going to make any further payments on this account.
