Nokia and Edgars - very BAD customer service

I had a terrible experience with Edgars Eastgate, I bought a cell Nokia 6.1 on the 29/08/18 seven days late I noticed a black spot on the front camera and the fingerprint was taking long to respond. I took it back on the 15/09/18 and I was advised that it will take 3-4 week to be repaired of which I didn't mind coz I was also advised when I bought the phone. I called them on the 4th week and they said no, it takes 4-8 weeks and now its the 8th week they telling me that Nokia has a backlog which means its gonna be 8-12 weeks now. this is very inconveniencing its 2 months now without a phone and they should make exceptions to make sure their customers are happy. I am not happy at all. What I also don't understand is why Nokia takes **** cell phones to stores for people to buy? no wonder they have a backlog I bought this phone thru my Edgars account and they've got nerve to tell me to keep paying for something that is with them.
