Wonga and Blake associates bad service

I am experiencing bad service from both wonga and blake & Associates

I had an query raised with both service providers as I had a loan with Wonga and was behind with payment and once i had funds on my accounts both companies debited on my account and was only left with one payment,

now requested a refund and i contacted blake they said i must contact wonga now with wonga i also raised the issue they said they will return to me within 3 days and its been over a week going to two weeks no response
