Sent from pillar to post-temp loan appears on app, cellphone banking and internet banking but gives error message each time

I am a very unhappy client. I have been sent from pillar to post since 4 April and now again since yetserday. I have been to branches in Sunward Park, Mall of Africa and Sunninghill. I have used secure chat and phoned them a number of times. My temporary loan offer appears on my internet banking, cellphone banking and my app. The error is always "This service is currently unavailable due to routine maintenance." "There is an error processing your request, a consultant will contact you shortly." This has been going on since the 4th of this month. I was then told by secure chat that Aspire can accept my offer for me telephonically. Aspire then said they are unable to do so and sent me to personal loans. I have also been sent through to digital banking. All with no assistance! I am incredibly disappointed. Dear FNB Do not advertise a product you're unable to assist with!
