Conn's Homeplus Collection Call Harrassment hourly starting the first day a bill is due Mesa Arizona

We were notiified in the mail of having credit approved with Conn's Homeplus so we went there to purchase some furniture in January 2015. 

We purchased a sofa and loveseat.  The soft started having flattening to the cushions after about a month's use. We have notified the store of that yet.  

As soon as the due day approached, we started receiving calls wanting our payment.  They will call every hour wanting payment.  You are given 10 days grace period, but they start calling the very first day the payment is due.  They not only call our home phone, they call my cell phone.  

We have always made our payments on time, and went there in about August to purchase a bed set.  The same thing, even though our payments are made on time, they call from the very first due date, every hour on the hour, until the payment is made.  This borderlines on harassment.  

Don't ever go there.  I am so disappointed. The sofa is ugly now, and I'm sick and tired of them calling all the time for money.  Not only that, the furniture is definitely overpriced. The same identical sofa set I bought is available at Big Lots for less than half the price.
