When i open the Davidzon phone card the recording announce I'll be able to talk for 57 min and conversation was only 40 min when t try to resolved the problem they told that they charge 25 cents for 2 weeks for service and 12 % tax. The card was used with one day and taxes on $5 card should be $0.60 when i calculated it was $1.20 and they did not want to resolved the problem. Thank you.
