For the promotion of the purchase of my Galaxy Note 9 they offer to recover an old phone Galaxy Note 4, they wanted to renegotiate the price, because of a really small peak that we have to take the phone in front of his eyes to see it. To which I asked that the phone be returned to me. The big surprise, he sent me the phone with the battery, while I had provided them all !!! (charger, box, earphones, headphones rubbers, the clip for the sim .. really everything.Samsung should review with whom they work or monitor their providers.
