Worst experience ever

App**** to get my revolving credit increased.After it was approved I was told the funds would be available within 2 working days.After 2 working days I had to phone and ask why is the funds not available and they told me there are outstanding documents that I had to upload.After I went to the branch and uploaded the documents I phoned them again.They said the documents are refelecting on their side and they will get the sales team to contact me.I phoned 6-8 times after that the following 2 days as no one phoned me from standard bank and all they had to say was they will get someone to phone me. I eventually received a call from them but its a week later and the funds are still not available.The excuse now is that they have system problems.They will phone me on Monday to if the systems are up and running.What a terrible experience
