Settled loan but still getting calls that its not settled!!?!?!?!

Hi so I've notice some similarities between my situation and what I've read. I've never had any problems with wonga until now- I've paid my my loan fuller that I made last month at the end of November debit order. So I've recieved numerous calls and when I could finally call back to ones who are not private they said about the Blake accosiates and stuff and I haven't paid my account, I was shocked I sent them an email to proof the money is out of my acc so according to I have made it, it still apparently doesn't show I've made the payment. I wanted to make a payday loan but I can't due to it doesn't reflect that I paid it, so now I have people calling me and I have settled. I've called to ask what's going on bit the lady claimed she would get back to me and she didn't and I've sent emails to wonga and blake. But no response just an automated email response. I've been trying since Tuesday, is there any possibility that anyone can advise me on what to do. Or assist me please ?!?!
