FNB’s customer service is a mess

Their online service, secure chat and customer service is just Wow!!!! Tried decreased my o/d facility. The decrease button didn’t even work on my account. Then the frustration of getting someone to assist. Can’t even sort out an overdraft decrease and closing the facility over the secure chat or on Customer service phone. Waiting period 3-5 days for an error on the banks side. Like how they always offer to lend you money but when you need to close the facility they always take their sweet time. Customer service needs to do better. It sucks!!!!!!
