TFG SERVICE SUCKS

I've been trying to open an account at TFG for 2 years I'm self employed and they require payslips and bank statements, which I do not have! When I call the call centre I'm other put on hold or the agents are too busy, I've tried to email, I've explained my situation to 3 different agents and nobody can respond to me as to how far my application is, whether it has been approved or not! I'm very disgusted, especially because I've worked there before and have encountered this problem even when I was an employee at TFG! No manager is available to speak to me..
