Samsung M2070 Printer

We purchased a new printer towards the end of 2014. In April 2015 we purchased a toner cartridge and at nearly R900 and had been told that it prints btw 1*** copies. within one month the screen was saying that we needed a new cartridge. Cartridge was taken in to Save Hyper in PMB. Apparently as Samsung have lost R4m due to misclaims from others that their cartridges have been needed replacing sooner that they should Samsung now want to check the printer. Our printer was taken away on Friday 5th June and promised back a week later, 2 weeks later we still sit without a printer. We have contacted the Samsung rep as well as the staff member at Save but with a totally unsatisfactory response.
