WARRANTLY CLAIM SHAM

A wifi router was purchased on 25/11/2014. It worked well until August 2015, at which time we took it into the Bayside Mall branch with original receipt. Being under warranty, we didn't expect any issues and was told by the technician he would phone back in 3 days. 2 weeks later i returned, at which time the same technician informed me he hadn't even looked at it yet! A few more days pass and it is collected the day before i was due to leave town for a period of time. In November 2015, the same problem reoccurs, at which time we send the router back in on the 19/11/2015, this time minus the original receipt, but still within the 12 month warranty. We then took a few days to find the bank transaction to prove the date (once again, even though this had been done previously and should be on the system!). We are then told that even though we brought it in within the warranty period which we have proof, because we brought the bank statement after, this nulifies the warranty! They failed to phone once since the 19th to give us any feedback either! This is borderline theft! We now are R800 out of pocket with a malfunctioning router!
