Brother gaurantee not honoured - POOR SERVICE

Bought a brother multifunctional printer. Mustek has come to collect it 4 times because of a fault. This started last year in November 2022. Since then been able to use the printer for 2 weeks. The printer has been with mustek for more than a month now again. It is April 2023 now and we still have no printer. When they sell printer it says next business day support. They don't give any support
