FNB from bad to worse

i am currently having the worse experience, with FNB even doe that i have been dealing with this service provider for a few years now, i made a purchase on the 25th of may and the total sum was R 1942.00 and it was made in Nike SA outlet store Springfield park Durban , and i was charged again for that very same amount and the same store on the 13th July 2019 , i called FNB and was placed on hold from 12 am up until 16:45 pm i have had my phone loaded with a 110 airtime voucher then a 55 Rand airtime voucher and also the same goes for today i loaded my phone with 260 Rand's of airtime and have been placed on hold right up until now, i feel FNB services are getting worse by the day it seems that their is nobody that can help , what good is a slogan "how can we help you" if they are "unwilling and unable to Help" i need this matter to be sorted out A.S.A.P, if not i am going to paste this story all over social media and will change my service provider to another service provider that can assist,
