Service or No service

The reason for my 1 star is that I joined Rain with the new package of R559 per month. Since I received my 5G Rain router I have problem with connecting to the internet. However whenever I use my Vodafone modem and Huawei router it works perfectly fine. I submitted tickets twice for assistance without receiving any. Eventually I called from my phone, spent more than a half hour being transferred to 3 different people just to be told that the Network people will contact me. The 2nd person that I spoke to told me that there is a problem with the router therefore it must be replaced, just to be told by the 3rd person that they will call me back to solve the no internet problem with the router. I will advise any person thinking of joining to please be careful.
