Purchasing Prepaid electricity problems

Using the FNB website as well as the Cellphone App, I attempted to purchase electricity - 1 this morning and 5 times this evening. The Cellphone app merely reported an issue has occurred without any details so I attempted to purchase the transaction again only to fail a further 3 times, the 4th time I received a different error: \Daily Limit Exceeded". I called into the number provided on the error log and was directed to online banking. Agent tells me to try this online - so I tired online and was greeted with a message 3rd party failure.<br> <br> My problem is this: according to FNB there is a daily limit to how many times I can purchase prepaid electricity"
