non- existent customer service

urgant need of contact from support team, ive emailed the customer service with the ATT to Carmen as i was told to do by the person who reply's to their Facebook messages but yet nothing. heres my story.... i finished paying my account in march. but blakes are still calling me everyday. when wonga calls me and i pick up the phone the call drops. i have emailed wonga customerservice and cc'ed blakes in with the last statement proving my account is not in arrears. blakes has actually stepped up to try and help me but wonga cant even get back to me. funny thing is if you owe them money best believe you going to hear from them 5 times a day. this is NOT customer service as i cant even get a simple reply or an email address for a manager
