Sears Whynotleaseit Dishonest Byram Mississippi

I went into Sears and used their why not lease it option since I was in a hurry to purchase a lawn mower.  Mine had just broken and I needed to get my grass cut.  I purchased the weed eater cash and used their why not lease it plan on the mower.  The mower's price was $400-450, and I have since paid over double the amount of the purchase price.  I called the company and advised them that I wanted to exercise my buyout option on the mower.  I got the price of $186 to pay it out after I had made 10 payments of 62.71.  I accept the fact that after the first lease went out, I did not buyout when I needed to so I accepted that and carried on. 

The second time I called and spoke with a female who I told once I got paid I was going to buy it out.  When I called to actually pay it, the phone number I dialed hung up on me twice!!!  I am contacting my bank to reverse the charges and I will buy out at the price I was given or I will stop the payments all together until they contact me in person.  I believe that when you have leased and paid over the amount of the product, they should allow you to have the merchandise since they have received more than what they would have gotten if I had bought it outright
