Shocking

I am an exciting discovery policy holder. In Nov 2017 I added a vehicle to my policy. It took 4 weeks and weekly calls from my side to finalise this as there was am IT problem on my policy. No call from discovery, I had to call and then hold forever. In Feb 2018, I made a change to the policy - the same problem. It is now 3 weeks later - again various promises that they will call me back but I am holding on listing to the music . . . the problem has not yet been addressed.
