I purchased the Heargard for my dog Shelby for six months and was going to receive the Visa credit card for $25.00 in which I did, but everytime I tried to use it, it was declined. Finally I called customer service and the recording said I had thrity five cents left on the card. How is this possible when I never used the card. I tried calling but no respond, I called the bank and no response. I am very disappointed in this service, you wants us to buy for six months so we can get a $25.00 discount and I never received it or I did but it never worked. Maybe you can explain why this happened to me. My namae is Rita Montiel, and i go to Byram Animal Hospital with my dog Shelby. My phone number is [protected] to explain what happened that I could not use this card. I feel that you should send me a new card for my participation in this service.
