Rain continues to disappoint

It is one week since my last review of Rain internet service provider, and nothing has changed. They promised they would replace the router and sim, but I never heard from them again. I have sent a number of emails to the customer centre via their RainGo bot, and asked for them to call me, but sadly to no avail. Just silence. Pity their service has to be so terrible. I managed to call their call centre and spoke to an individual called Zaz who said she would escalate. Here are some of the reference numbers ***0 / ***4 / ***8. I received an email quoting the last reference number to say they had reset the router, but they did not mention which one. I have one working router and one that has not worked for maybe 6 weeks now. My issue is with the router S/N LUNDW***. IMEI ***. What drives me insane is that when I call the call centre, they start from scratch, they have no record of previous calls, or serial numbers or IMEI numbers. I have to quote everything to them over and over again Then last week after my previous post on HelloPeter and young girl phoned and asked me to please explain to her why I am unhappy, could I please share with her all the issues. Why was she not able to call me after she had done her due diligence, and with a solution? Useless company
