Magnum Cash Advance is Illegal and yes they are the same as International.
I had a loan with them. I sent my letter and when I stated I wanted to pay the principal via money order this is the address they gave me.
Mailing address:
International Cash Advance
C/O Call Center Services, Inc.
1403 Foulk Rd suite 203
Wilmington DE, 19803
That is only the address here in the states which is a call center and for payment processing. They are actually located in the British Virgin Islands.
I did not mail a letter I sent them an email using this address info(at)magnumcashadvance.com
They replied from this address Mgmt(at)mycallcenterservices.com
