However, after the issuance of paper vouchers by the carton machine, the seller swiped the buyer’s paper path and did not allow me to check the amount posted.I considered this type of attitude strange and requested the delivery of the proof. The seller declined to deliver the voucher, so I took the paper voucher (via the seller) over the counter. At this time, I noticed that the amount posted was $ 1,306.44. I questioned the difference between the amount posted and the final value of the purchase.The seller, a guy said that his store was an authorized reseller of the "T-Mobile" phone company and explained that the difference was a warranty from the T-Mobile company that the smartphone and the Apple watch would not be used / enabled at the AT & T phone company. Said I could not use the AT & T chip on the purchased smartphone. I considered this type of situation inappropriate, so I requested a refund of the amount paid with the credit card. At this point, the seller informed me that it would not be possible to make the chargeback. I insisted that he take the chargeback, he was rude and said he would not make the chargeback.I felt that my physical integrity was at risk inside the store, I retired with the products purchased mentioned above.Upon arriving at the hotel I was staying in New York, I searched the internet and found several reports of similar blows applied in the same store by the two vendors involved in this occurrence. On 10/31/2017, early in the morning, I requested the cancellation of my credit card with my account manager.
