Dollar Tree

I was told by an employee at the Dollar Tree Store #104...6929 John F Kennedy Blvd, North Little Rock, AR... 72116, that the gift card I would purchase was like a visa and could be used at any store...I purchased as a birthday gift on Sunday, December 2, 2018...gave to my friend as a gift...my friend informed me that the card could only be used at Dollar Tree...I called the store and talked to the manager on December 4 and was told they could not take it back...even if I was misinformed about it. She gave me a number to call...[protected]...I have been calling this number since yesterday...holding on the phone over 30 minutes each time...no person every answered...i would like to return the gift card for a refund...your immediate attention is greatly appreciated, Rosie Tilmon...my phone number is [protected]
