Terrible service from Rain with connectivity and billing

Ever since the change over to Rain one I am having endless issues with Rain in general. If it's not my network connection then it's a billing issues. It never ends with Rain these days yet everything was fine all this time. Why go and make all these changes when they cannot cope with the load. I have a 100mbps line but these days I barely get 5mbps on my network connection. It is so terrible these days that my teams meetings are always freezing. Also I changed my billing date to the 1st of every month, 2 months ago but I still get messages and disconnected by the 25th of each month. This is really bull**** cause I rely on my internet connection for business purpose. If Rain continues with this terrible service that they are offering now then they will never progress as a business. Get your ducks in a row Rain, I never had such problems ever in the past but now it's becoming a daily issue with you and I don't have the time for this to keep contacting Rain about my connectivity or billing issue. IT IS NOW BECOMING THE WORSE NETWOTK IN THE COUNTRY.
