Instant Payroll and Enterprise FNB - - be aware of Poor service

I migrated two of my business accounts to the Online Business Banking Enterprise at FNB. I am a user of Instant Accounting Solutions and Instant Payroll. I specifically enquired if this migration would impact the data captured on this and I was assured by Mr Mark Francis that it will not impact. However after the migration both these systems were not available - I managed through the call centre to link my Instant Accounting data for both companies, but I logged a call on 6 March (a lady called Larisha) to also link Instant Payrols. She was not very friendly but told me to send some screenshots to her for both companies and she will do it same day. I needed this as I had to make some salary payments and get the IRP5's for previous year. Since 6 March I made 7 additional phone calls, send the same e-mail several times, had the call escalated to senior management but to date it is STILL not linked. 10 young people are not getting paid due to FNB's incompetence. On Monday I had a call telling me everything was sorted but when I got to the office and checked it was not - I again escalated the call and 10 minutes ago (on 12 March) I got another call telling me it is sorted. I asked the lady to stay on line so I can check - she refused as she was "too busy" but assured me it was fixed - well it is STILL NOT fixed. I called the line again - got hold of (by chance) Larisha again - she listened to my complaint and then dropped the phone!! I don't know what else to do!! Be careful with FNB - they can destroy small business with this poor service!!
