WICODE technical issues

I am honestly so tired of calling and sending emails anymore. I orders Debonairs using WICODE and twice the transaction did not go through, I was charged for both transactions and when I called customer service they said it will rectify itself after 48hrs, it did not, I called again and was told it will rectify itself after the 12th of January I must wait, waited and it did not, called again and was transferred to Merchants which they said I must send an email with proof, I asked them where should I get proof as the transaction just did not go through and there was no error message nonetheless I sent that detailed email as per their instructions, till to date no feedback, no care in the world, they just ignore emails. From the 5th of January till now. I was charged the amount I did not spend and there’s zero customer service. I have lost hope, I will just pay off this card and close it.
