Rain Connectivity Issue

I recently moved houses, I contacted Rain to inform them of our new address and assistance to configure our router to a nearby Rain tower. Since moving in on the 15th of December, the connection has been really poor if not at all. We've tried every trick, placing the router near windows, facing it in the direction of the nearest tower, rebooting etc. We have little to no connectivity with the router inside the house, however, outside the house we get a good connection, even 5g which is strange considering one the agents I spoke to said there's no 5g in the area only 4g. I've called Rain 4 times since this past Sunday the 17th of December regarding this issue. On Monday the 18th of December the agent I spoke to informed me that she will escalate my query to the Networking Team. Apparently the networking teams turn around time to attend to an escalation is 24hrs. After more than 24hrs I followed up with Rain today the 20th of December and the agent I spoke to advised that they will follow up on the escalation and provide feedback during the course of the day. It's now evening and have heard nothing from either the agent or the networking team. I work from home and need a constant and stable connection and cannot afford to have spotty or no internet connection. The service received these past days from Rain has been nothing short of terrible.
