bad service

I app**** for rain internet since last year and its been giving me problem ever since , i ended up calling them and sending emails to them. Around August they sent a technician and i was told that, the Wi-Fi doesn't connect due to pick hours and id still have a problem even in the morning. The guy advised me to keep the 5g outside so that it can connect to everyone in the house. The same thing occurred over and over. I used to call everyday i ended up speaking to a senior manager Dean Jackson who informed me of the refund that i need to get but still i haven't heard from him till 2 day he called me on the 15th September 2021 , today its the 29th September 2021. This morning I've been having a bad connection and its not only 2day. I'll never advice anyone to take contract with Rain and the level of service is shocking. i I've spoken to several supervisors and it makes sense why they are like that.
