Mobicred dont know what they are doing! Very angry

Hi how many times do i have to phone your customer service i phone 6 times already i was told that i app**** in 2017 and i did not have a good credit score THEN so when i app**** now in 2019 i still dont get aprroved. Phoned customer service was told by different agents that it is because of the 2017 application the matter has been sent to the accounts department they will fix it and send me an email stating i should apply now. Never recieve such an email worst customer service as evey single person i have spoken to said it is because of the application in 2017 and that that application needs to be removed by the accounting department then i can re apply. So whats going on now.3 months later still no email still noy able to apply
