stuck and go network ,more restart than nothing

I'm not to sure as to what is the problem I logged a ticket in the week *** .I'm experiencing problems with my rain router or signal. In the week I logged a ticket and all of a sudden I received a web optimise with out my permission a extra r30,first of all I did not request to have a web optimize to bedone. My problem is my router has to be restarted every day almost 10 times a day to at least work ,the signal is horrible stop and go all the way in the evening it is more horrible from 15hoo too 20hoo I do not have quality network. Please let me know what I'm I to do with this as I can not afford more than the r499 and now it's a r30 more which I see no difference the speed from 25mb to 30mb the problem is still not resolved

Please let me know what I'm I to do
