Pathetic service

Contacted FNB regarding my faulty LG G4 With the boot loop issue which LG confirmed is a manufacturer fault. Now the phone is nearly a month in for repairs and still awaiting parts to be repaired. FNB you can seriously take this up with LG to replace the phone, cause you are my service provider. A month has passed and still waiting for parts and you expect me to pay every month for a device I don't even have. I will never purchase a phone or never the less a LG phone from your smartphone department. Can you please sort this out today still. The ball is in your court now. P's! I did contact the repair centre directly in Pretoria (Let's trade mobile) that's how I know that they are still waiting for spares.
