Bad service and incompetence

I have a home loan with Nedbank, I was debited twice for this month,I spoke to them yesterday, they said they will reverse the money as soon as another payment from my employer appears on the system.Today the other payment is reflecting now they say I must wait 3 days, I’m frustrated as they have been taking me from pillar to post and consultants are so *********** because they give wrong information,I have been with Nedbank from more than 5 years but customer service is really bad, I need to find a reliable bank and switch from Nedbank
