Terrible service after a year of being customer,I am so disappointed

I have been with Rain for a year today,On the 26 April 2024 I phoned the whole day to swop the old device to the new device.I was taken from pillar to post and eventually I started asking for reference number for the calls.I complained to retention and I was given 50% discount for my old device and told them I learnt of a promotion in sales of a R19 Rain101.I asked retention to send me a link so I can the 50% and I waited the whole day.Eventually I was told that the is a problem with their system and they could reconnect my services since(I pay on the 26 every month)On saturday I managed to pay 50% without the link and asked support to connect me and still I could not buy the new rain101 because the system was still down.Yesterday my services were disconnected again.If I don't get help today,I am going to report to the ombudsman.I am receiving a terrible service
