Double Debits and no apology during December

I am very disappointed with Atlas on how they left me out of pocket in December. I had two debit orders and to my shock and horror I was debited 4 twice (each debit twice). Went off on the 15th and then on the 17th. I phoned the call centre and I could not be assisted. I was left stranded and could not go home this Xmas. I have debit orders running tomorrow and have no money left because of this. This s shocking. I have never experienced this in my life. They will probably tell me about some turn around time to reverse my money.
