Poor service.

I app**** for a loan at Wonga. I received an sms from my bank that I must approve tne debicheck mandate, I did two days ago. I went onto wonga site and it still shows I must accept the mandate, but the loan is active on my banking app. My status hasn't changed. I tried calling, no answers. Wrote emails but no response. This is bad and I haven't received my money yet.
