Took my grandson's cello in for a free inspection after paying off the rent to own contract. It was cleaned up and adjustments were made for a charge of $25 which I paid for with a credit card. Two days later I received a warning alert from my bank indicating there was a suspicious pending charge to Amazon for $1. I immediately canceled my card and had the bank reissue a new card. The strange thing is that it was the first time I used that card in over 8 months.
