Poor service received and disrespect

I initially app**** online and when I app**** I was never told about any verification but all went smooth,then days later I received an sms to log online to accept my offer,,then I tried registering online but ut shows I have an account then I did a forgot password but im not getting pleasure tried calling the callcenter more than 5times they kept telling me they cant authenticate me because im not receiving a pop up message,they kept telling le its their system error couldnt they use a different way confirming details cos its not my fault im not getting the pop up message fine all understood eventually the consultant asked if I can go to the branch fine I decided from work let me go to the branch cos im not getting pleasure,,I got to the branch at 16:58 the door was closed I waved inside the branch yhuuuuuu the lady was soooo rude then the lady cleaning tried to show her that theys someone at the door but she just gave me a dirty look,,While I was still waiting there trying to contact the call center again she came out and I asked her lady could you not come to the door and atleast hear what I wanted to ask yhoo the way she lashed out at me started telling asking me what was she suppose to do when the door is closed,I demand an apology from that lady shes rude and doesnt even know what customer service means how do you speak to a frustrated customer like that,,if she does not personally apologise I will take this further.I called the callcenter again and still no pleasure but Im more annoyed by the branch consultant from Birch Acres Mall
