Friendly staff, bad service

I received my 5G router and sim on 9 September, which was very satisfying as I got my order within the promised period. After this I have been having trouble with Rain as I still do not have a connection to the internet and it is the 15th already. The support team have been very nice and understanding, which was much appreciated but I am very disappointed in the network team that has apparently been working on my problem since the 10th and I still have not received any feedback or change in connectivity. I honestly hope my situation can be resolved before this week is over as I need internet to work from home and will cancel the service if I cannot be helped.
