Cannot activate Holiday Home

I am VERY tired of the DSTV App never working as it should. I cannot activate my Holiday Home decoder on the app; when i try and save how many days, it just goes back to the question of how many days do you want? Neither can I activate it via the DSTV website - there is no option to do that there, so I have to call in to the DSTV Call Centre and we all know how long those calls can take. Frustrated beyond! This particular issue has been going on for 4 weeks now, but if it is not this one, it will be another issue next weekend.
