FNB going from bad to worse - Prepaid electricity option no longer reliable!

I must say I am really not impressed with the way FNB online and support services are going at the moment.. It seems to be going from bad to worse (private client bankers assisting several thousands customers in their portfolio)! : so much for offering private bankers in exchange of paying substantial fees for services not provided (9 out of 10 phone calls requesting assistance going to voicemail). Also, for several times now, I have been trying to purchase electricity through the FNB app (both on mobile phone and through my MS Windows Desktop) and I am not always receiving tokens the way I used to i.e., right away.. it is now often taking a long time. For example, I just bought R1,000 worth of electricity 2 hours ago and still nothing came up, no token received nor any purchase showing in my transaction history, and I cannot try again to buy any as it says my daily transaction has been exceeded despite me upgrading my limits temporarily. This is unacceptable!! it is 2:00 am now and I am running out of electricity but I am unable to reset my counter and this is not the first time this happens. Who is responsible for that? *********** people/ inadequate Token transaction system at FNB? Eskom? please advise, this is extremely frustrating and it never used to be like that! what is going on at FNB? Should I look into doing business with another bank?
