Rent-A-Center RipOff Fraudulent Rude Un-Professional Constant Harassment Las Vegas Nevada

I have been renting to own a 51" Hitachi Big Screen with Rent-A-Center for over a year now. I have been late on my payment several times, but as of now I am past due $16. I asked them to pick up the merchandise because I pay over $200 a month and for over a years time they say I still owe them over $1500. My main problem is they call 6-8 times a day for $16. I tell them i'm out of of town and can't get back until a certain time and they call my grandmother and mother after I repeatedly went into the store location and asked them to remove my mother's number because I haven't spoke to her in over a year.

They assured me at the store level that her number was removed yet they call her and my grandmother 6-8 times a day still. I asked the store manager why they would lie and keep the number and his rebuttal was why did I lie and late my account become late. Things happen but over $16 is ridiculous. They are harassing me and my family and i've asked them to stop and pick-up the merchandise now and now they aren't calling i'm not sure what to do from severe harassment to nothing. Now I wonder if they are going to take me to court. There manager is very rude and argumentative with me and i'm not sure how to approach this anymore?
