They said they would resolve this issue, but I am still getting calls form their Blake

I brought this issue to Wonga in January, they said this issue was resolved and I stopped receiving calls for the rest of January but I am now getting calls again for February.

Wonga double debited me in December, first debit order being early and then again at the end of December, the second debit order bounced because I had not expected the payment and only had enough in to cover my expense, hence taking out the loan.

Initially it took 2 emails to get them to respond and reverse the debit, which they eventually did, but then put me on a non payment list with their outsourced debt collectors blake.

My wonga account still says "You are in default and interest is continuing to accrue on the outstanding amount." even after it was their fault that it is like this.

Secondly I keep getting calls from Blake, I have reached out with multiple emails to wonga but do not get a response on any, Blake they keep saying they will correct the error on their side, but I get the calls now every second day, I work a night shift job and they are constantly calling me awake.

How badly run is this company that they cannot even resolve the simplest of tasks, It is honestly ridiculous.

My patience with this company is wearing very thin and will never use them ever again.
