Extreamly poor service

I app**** for a smart device and now want to make a cancellation on my application and i have not taken delivery of the item. I have used up over R100 on airtime with no joy. I called the call center numbers provided to me ********** 270 and spoke to mamusi and lehlohonolo who have been putting me from one line to the other until lehlohonolo decides to give me another number ********** 800 and spoke to yet again another person namee Busakwe who decided to put me back to the previous call center with no help again. Everyone is just transfering my call till i ended up at the credit card department and back to the sales call centre again. This has been going on for 2 days and still not through to the relevent people. FNB is now starting to become a liability with poorly trained or *********** staff who do not know their relevent channels
