ABSA notificatons are the pits

Both my husband and I have Platinum cheque accounts with ABSA and for the last 8 months have had the worst notification service ever. Nobody seems to be able to resolve it. On a recent holiday, the holiday money set aside was completely messed up because notifications were not received and balances not updated, double debits occurred at numerous vendors, resulting in a shortage of funds. Sunday swipes are coming off this morning, Wednesday!! Unfortunately, ABSA tried to defend themselves and say it was my network - and yet my husband and daughter, who was here on holiday have exactly the same issues and we're on different networks and on WIFI at home and then saying it was the vendors themselves who were banking late - this has nothing to do with notifications!! The notifications are there for a reason - to prevent ***** and keep us updated on transactions and available balances. Disgusting service - family have had enough and will migrate to other banks.
