Terrible service from Telkom

I upgraded my LTE WIFI in October 2018 and I have had a problem every month with getting internet access. I have to call for help and get all kinds of reasons for the problem and then a week into the month I finally get to use the internet. There technical support and there billing department are totally use-lance. And if I try cancel the contract they are going to give me issues even though they do not provide the service properly.
