Bad and Utter Pathetic Service from Limit Increase and Customer Relations

So 3 weeks ago I made a purchase at Edgars on my Jet account and I was informed that I qualify for a limit increase and that I need to submit 3 months payslips. I did this on no more than 4 times since the 9th of July and all you get is the useless reply that states we will get back to you within 48 hours. After getting frustrated to a point I actually sent an email to customer relations and after days they came back to me and said I need to send my July payslip which I did and now its a waiting game again.

Can A company be so pathetic and non customer orientated like this , its pathetic and poor

Regards

Martin
