A faulty router hasn’t been replaced in 2weeks

I submitted a faulty router and was told it would be replaced , it’s been over a week and there hasn’t been an update. I went into the store over the weekend to check if I could get a loan device because of the urgency, but they said they couldn’t assist and I’m on contract. I’m now spending a lot on data as I work from home I’m also going to be expected to pay in full at the end of the month this is ridiculous, replacing a router cannot take this long , this is the second time and when the router was assessed no damage was recorded it’s disappointing that I have to wait so long and it’s a huge inconvenience caused.
