Bad attitude an Poor Service from Fnb Call Centre Staff

I had a pending amount on my Fnb Credit card that was supposed to be returned back to my Credit card but the amount was not returned to my credit which would change my current balance and I have been transferred to about 9 different staff members from different department, as soon as they realised they could not help me with my query they would tell me to hold, which then they would just transfer me to another department, were I would start again explaining my query with no resolution to my query. I spoke to customer service, collections, authorisation and other departments. All could not help me with my query. I just kept being put on hold and being transferred to another department without the call centre agent getting back to me. Some of the call centre agents were really rude and would just tell me to hold as if they are going to inquire about something yet they would just put me on hold. This is so frustrating as my query is still not resolved by FNB.
