Istore Disapointing

I went to tygervalley Istore on the 19th of July , I went to a girl and she assisted me but because its her lunch time she asked someone else to assist me, The girls name was Donay , She was friendly but to be honest I did not think she could do her Job , there were times when someone else came to assist her and this was the issue the staff do not seem to be trained or know how to handle the systems when it comes to credit vetting. what she did was then opened one line and then created another line later one which then resulted the credit vetting to decline me. Firstly the staff is not trained properly and some can be very unfriendly . She called me when she told me it was declined. I then filed for a online application which resulted in the consultant said I need to email my bank statements and then he continuesly told me to mail them but there was no mail that he ever asked for it as I am on my mails 24/7 so there was never a email and I did send him a screenshot as proof , why would I upload the documents online and then have to submitted it 3-4 times again to the their email adress but they seem never to receive it . It amazes me that nobody can call you only email. This is pathetic service and honestly disapointing.
