Disguated at the service of the call centre

I app**** for a credit increase to which they told me I have to go to their store ,I went and then when I called them as there was no feedback ,they told me there was missing documents of which I had to go back to the store , 2 days down the line I speak to a call center agent by the name of Thembie who keeps interrupting me without even listening ,she is very rude and worse ,I ask her to put me through the manager and than she puts me on hold for over 10 minutes ...Foschini for such a big company I am disgusted to say the least
