Stop avoiding issues

We are trully very disappointed. So we have been having issues with our signal for multiple weeks now. We have been contacted and we tried everything. At a point one of the consultants even told my partner that he should rather just cancell his rain account. After complaining about this we then received a call from someone that tried to assist. We where advised that our sim keeps picking up the furthest tower and that he will escalate this so they can try and get the sim to connect to the tower that is +- 1km away. No one came back. We decided to buy a Antena to assist so it is pointed in the correct direction but stil the sim only connects to the furthest tower. So I decided to log another ticket as no one is getting back to us. Finally got a call a day later and was advised they will follow up on the previous ticket. Then we received a mail stating we need to move the router in the direction of the tower. And that a mail will be sent later so the ticket may be closed. So my question is where is the phone call? We have done this and so much more! So please let us know if you are going to get this sorted or are you going to keep avoiding issues ?
