POOR CUSTOMER SERVICE

I asked TymeBank to send me the proof or letter to confirm that the card was cancelled, unfortunately they said they don't issue the letter for cancelled or stopped card, but they can write an email, they did write an email that said "The card on their system it shows that it was stopped due to lost" but they didn't put the card number in their statement, I've been asking them to put card number on their statement several times they are failing to do so I'm making follow up via email but their ignoring me no one is attending to my matter, IT IS NOT THE THE FIRST DOING THIS TO ME, THEIR CUSTOMER SERVICE IS VERY POOR THEY PROMISE TO REPLY TO EMAILS IN ONE DAY BUT THEY ARE FAILING TO GIVE THE CUSTOMERS WHAT THEY PROMISED.
