Bad ass service!!!

I bought a skirt from Legit Gateway last week Friday I paid using a card and the money was debited twice from my account the slip didnt come out of the speed point/ the machine after making the payment. I was told that I need to get the statement from the bank that proves that the money was taken from my account and I did. The lady from Legit told me that she will sent an email to the finance department something like that. She said she will send it on Monday. I followed up on Wednesday I was told that the money will be in my account later on that day but till now the money is not in my account it's the 6th day today. What does one have to do to be taken seriously from Legit and be assisted because it's been long enough now.
