Good customer service resolving issue quickly

I started using a Rain 4G sim on the unlimited offpeak offer, in early April. I was very happy with the service, until the last two weeks or so, when the signal started dropping regularly. It got really bad this past week, so I posted a query on the MyBroadband forum, to see if it was just me or if others were having the same issue. A consultant contacted me on that platform almost immediately, on Tuesday late afternoon. He then checked in on Wednesday to tell me he was still awaiting feedback. I then wrote again on Friday saying the problem was getting worse, and I got a call from an agent on Saturday morning explaining what they had done. Since then the problem appears to have been resolved. So I just wanted to compliment the company on what was pretty good customer service.
