NEW ACCOUNT HORROR

I app**** for an account online and received an email indicating that i must forward my payslip/bank statement to the nearest store.I went to Kempton Park square Ackermans to hand deliver my statement on the 2nd May 2019 and i waited for a response which i know it takes only 48 hours to get back to the client but i still received messages indicating that i must send my documentations again.On the 10th May i received a call from the head office informing me that they are still waiting for my documentations,i then went back to the store to submit again at Kempton Park square and they scanned my papers.Today i call the head office to check if the received my papers after a long wait they inform me that they have not received any papers,i must again go back to the store.I called the store and they said i must go to another store and try to see if the papers will reach the head office because another customer also had the same problem as mine,they say the head office is saying they never received the documents while they have scanned them.So who should assist me because i cant be running around like a headless chicken going up and down.This is BAD SERVICE TO CUSTOMERS ....
