Angry and unsatisfied customer

I have been with this network provider since 2021. Just recently my network router was damaged, I had to order another one and pay for it. I ordered one and paid for it in Mayand waited weeks for my new router to be installed while following up with their *********** customer care. Finally they came to install it somewhere in June while at the same time I upgraded my package from 10mbp to 20mbp. Since receiving my new router and upgrading somewhere towards the end of June, I have been struggling to connect to the internet, it's the same as not having wifi. I called again and now it's the 21st July and I still do not have internet connection, I have followed up on this matter and still receive no assistance. I don't think it's something that they can not sort out, it's is just bad service and I am ****ed to the core 😡😡😡😡😡😡😡😡😡
