Walk-in-Centre closes an hour before it supposed to

I have been having decoder issues over the past month. Have had to go out to the Walk-In-Centre on 3 occassions. Not the most pleasant experience with the long lines due to Covid checking but I did what I had to do and waited. Today I called in and was told to come in. I know the walk-in-centre is opened till 6pm but confirmed this with the agent and on DSTV's site.

I rush to get out of meetings to get there by 5pm thinking an hour should do. When I get there, I see cars trying to get in to no avail. Eventually all the other cars left and I parked at the gate, hooting for attention but was ignored. I tried to call the call-centre that I called not too long ago and went through the same process of entering my ID. This time it goes in a loop asking me for my ID over and over. So I wasted not just my time & fuel but my airtime too. I was @ my home @ 6pm with a broken decoder and nothing I can do about it. Horrible service.. I am not impressed
