Very bad service

We are so fed up with WesBank. We have been struggling for almost a year now to try and get the ownership documents of my deceased mother's car. We have sent them several emails, when you phone it takes 40 minutes before someone answers only to hear that they cannot help over the phone. When you send them emails it takes 3 days for them to response and every time it is the same respond stating that they require certain documents. The documents have been sent several times, we even did a payment which they required back in April and still we are waiting for the papers. I won't finance with WesBank ever!
