BatteriesPlus review: rayovac cordless phone battery # tel 10213

Purchased this battery on 9/ 25/15 between 11:00am & 12:00 noon. Man told me it was most likely the battery causing the problem. Cost was $16.00 even. Put it in cell phone on 9/27, phone still did not work. Messed with charger, and the plug, apparently was loose or something. I moved it several times from side to side and it started working. I could not find the receipt anywhere, and am not really sure that he gave it to me. Just don't know! I went to the store 636 S. Stratford Rd. W-S, NC 27358. I went to store 1st chance on 10/3 and explained this to the man. He gave me no options, no receipt no discussion! I don't think this is right. They say they want us to trust them ! Really
