You never go through to their Contact Centre

I called the ***last week on Thursday just after 08h00 and I held for 8 minutes to go through to the agent, eventually I could hear that I am through and I waited for someone on the other side to say Hello or something. nothing happened for over 48 sec and the call was cut. I then call again stayed on the line for 12 minutes this time and again I went through only for my call to be cut after about 52 seconds.So this morning I call at 11: 00 and after a voice recording says \ please note the department of the compensation fund does not operate on Public holidays"";I am expecting that already when I dial your callcentre number. but this is just too much."""
