Disappointing service👎

I've recently relocated & needed to switch my fibre, spoke to an advisor on the 20th of October, tried to get it sorted out.. Around 2 weeks later I called to cancel my subscription however spoke to someone from the retentions department that offered a substitute(LTE) while I wait for fibre installation. So they delivered the router only with no sim card or ****le. After calling numerous times they finally delivered the sim card after a week however the sim card is not activated, called in twice already & they just say they will give me feedback. It's already the 20th of November.. How is this even a substitute. Still waiting for feedback.. Very disappointed.
