bad services, *********** staff and system23

i have created scheduled payment on 14/07/2018 for payment to take place 24/07/2018. i have cancelled that scheduled payment before 24/07/2017 as i made manual payment nor debit order was going to collect for that service provider. i have logged a request with FNB on 17/09/2018 to give me transaction history of above story took place on 14/07/2018 until date nothing came through. i have visited the branch then i was taken from pillar to post ranging from sales consultant, online banking, ***** department, Enquiries etc. The last consultant i spoke to on Monday promised to escalate my matter to IT department as they are the only team to assist with such queries as it need back end system and was furnished with reference number and promised feedback 3-4 working days, until date i haven't received anything. i decided to visit the branch again on 20/09/2018 after receiving correspondence from sales and services resolution team advising me to contact Enquiries online for verification purpose and my request will be actioned, i had to start from scratch explaining my request and consultants couldn't help after spending about an hour on the phone my call was transferred back to the Que and got cut off. i really fail to understand how can such big entity like FNB fail to assist customer with a transaction history of the account.
