Discovery bank frustration!

Logged a query september last year for my vitality money to be sorted. i phoned this morning again and the lady that i spoke to just cancelled the call. This is so frustrating to deal with a bank that doesnt have your best interest at heart. The latest reference number i have for this query is ***. They also never come back to you, YOU have to get back to them if you logged a query. Frustration beyond frustration.
