No help from Roku. TV won’t stay connected to wifi

Someone was trying to assist me over a month ago and has not responded to me since June. My tv is not staying connected to wifi. I have to reset this every time I turn my tv on and off. This is very frustrating! Why is no one addressing this? I am looking for a solution to this issue. I’ve already provided my device and internet provider. Not sure why no one is responding and this has taken a month. I am about to buy a new TV and it will not be a Roku one since no one seems to care to assist me or address this issue. I’m also not the only person who seems to be having a problem with this.
