Conns Home Plus The Store Representative (George) lied to me about the payment amount to completely payoff the account within the no tax period. San Antonio Texas

I went to conn's home plus store and bought a sofa and love seat.  The sales man george advised me that inorder to not pay any interest within the 18 month period, instead of paying the amount on the cupon book, to pay instead $265.00 a month and at the end of the 18 months the account would be payed off and i would have payed no interest. 

I received a letter in the mail from conn.s indicatind that I was going to owe over $800 dollars on my account plus all the interest from day one when I bought the furniture.   

I contacted the beaumont office and they tole me that there was nothing they could do.  That it was written in the contract.  

THIS IS A TOTAL RIPP OFF..!!   NOT ONLY DID THE SALESMAN LIE TO ME ABOUT THE AMOUNT I HAD TO PAY, BUT HE DECEIVED ME INTO BUYING A SERVICE CONTRACT.   

WHAT MAKES THIS MATTER WORSE,.....IN JANUARY 2018, I FILED A SERVICE REQUEST TO HAVE MY COUCH FIXED BECAUJSE THE SPRINGS WERE COMING THRU THE INSULLATION WHICH MADE THE COUCH UNUSABLE AT ONE END.   

This was January that filed this request, finally this month (May 2018) Conns contacted me that the sofa was not fixable.   This was after their service people had been to my house two different times and were not able to fix it.  

What conns didn't care was that this problem with my service had been going on since october of 2017.  So when I finally made my report in January 2018, the couch was not usable.  

SO I WAS PAYING FOR A SOFA THAT WAS USABLE AND STILL BEING CHAARGED FOR A BROKEN PRODUCT FROM CONN'S 

NOW CONN'S TELLS ME THAT I BETTER PAY OVER $800 DOLLARS BY JUNE 23 OR I WILL HAVE TO PAY INTEREST FROM DAY ONE OF MY PURCHASE.  

CONN'S HOME PLUSS IS A RIPOFF AND THEY COMMITTED FRAUD WHEN THEIR SALESMAN INSTRUCTED ME TO PAY $265.00 MONTHLY AND I WOULD NOT HAVE TO PAY ANY INTEREST FOR MY PURCHASE.   A TOTAL LIE...,....!!!!!!!!!!!!!!!!!!!!!!!!!!!!

i AM A 100% Disable Vietnam Veteran and I do not deserve this type of treatment from this Furnithre store who does not care about customer service.   

THE SALESMAN AND WHAT HE TELL THE CUSTOMER REPRESENTS CONN;'S AND EVERYTHING THAT HE TELLS SHOULD BE TRUTHFUL.   

NOT IN THIS CASE....!!!!    NOW I MUST SUFFER THE CONSEQUENCES FOR HIS MISTAKE, OR LIE....!!   

THEN THE FACT THAT THE SOFA WAS NOT USABLE FOR OVER 8 MONTHS AND THEY STILL GOT PAID, IS TOTALLY WRONG...!!
