Showmax billing sucks.

What a halfbaked streaming service and billing site. Signed up for mobile but realized I want to rather upgrade to also include TV as I am booked of sick. Need to cancel subscription and wait a month to sigh up again. Why no option to simply upgrade and do a topup pmt? Well you might have had me for life but now you scored a R45 bucks once off but no return. Rather sigh up somewhere else.
