Pathetic Service - No Whatsapp

I called in this morning as my whatsapp is not connecting. The agent assists me and advises that when I put the phone down it will be ok. Not to my surprise it is still not working. I call back, the next agent hangs up on me! I call back - by this time I am frustrated. I ask the 3rd agent if he can see the notes that have been left on file. He puts me on hold and eventually comes back and tells me 'I will assist you'. Assist with what. I ask again if notes have been left - he tells me 'no'. How does one follow-up queries if no notes are left? I then request to speak to a manager. The same old story is given 'my manager is currently unavailable'. If your manager is always unavailable who is running the call centre? Not surprising with the **** service paying clients are receiving. He then puts a 'second in charge' person on the phone - who thinks I am illiterate and keeps repeating that her manager is in a meeting. I told her that she should find another manager then who can assist. Eventually I decided I can't speak to ******** people. You would think that my call would be escalated to a manager or at least the problem be fixed - I guess I am asking for too much!! Still no whatsapp
