Trash after sales service

It's been 3 days and I'm still struggling with getting help to get my router working. I recieved my 5G router on the 28th of April. Yesterday on the 29th of April I spoke to 4 different consultants without any hope. I just got off the call with another one this morning and she told me that the billing department should load my data. Honestly that can't take 3 days just to activate someone. I'm not happy with the after sales services
