Bad technical support

I've been with rain for a couple of months now. All of a sudden my Internet from my 5G router has been dropping since Friday the 17th of November. I wasn't alarmed so I left it for the day and called support on the Saturday. The time on hold on the phone was very short and the customer support was very friendly. She guided me through possible steps to re-establish the connection. When that didn't work she said she would escalate the matter to the technical department. She assured me that if I did not hear anything from them that day I would be contacted by Sunday. I did not receive a mail or any contact from the technical department and by now being without WiFi I had used up all the data on my rain sims. I called on the Sunday again when the friendly customer support said she can see it has been escalated however it may take up to 48 hours to reach the technical team. I told her it was understandable because most people don't work on Sundays. I asked her about any way she can help with my lack of data and she said unfortunately there is nothing she can do. I called once again today (monday) after it has been now 48 hours since my first complaint on Saturday and I was told now it could take 72 hours. I work from home and now running on mobile data is getting pricy. I don't understand how many other ISP's have technical teams working on the weekend but rain does not. Apparently people don't need Internet during the weekend. Very displeased at the lack of actual help and sick and tired of always having to call rain from my side and explain my story everytime. Definitely keeping my eyes open for other ISP's.
