Defy Polokwane center ****** ******!!!

I bought a defy microwave at Polokwane game a year later the start button stopped working. Took it in for repairs no problems given as the microwave was still under warranty. It was fixed and the report stated that the microwave was HANDED IN FOR REPAIRS IN GOOD CONDITION. Less than 9 months later the same problem starts the start button stops working. I took it back and now the repair center claims that ****roaches are the cause of damage and that the microwave is no longer under warranty so i must pay. They even went to the extent of sending false pictures trying to prove their false story. Cos 1st of my house has no ****roaches and that is an insult . Why wasn't i told about the ****roaches story the 1st time it went in for repairs? But now that its their repairs that didn't even last 9 months and because the microwave is no longer under warranty cause of damage is ****roaches. Which is a total lie and their false pictures ****** crocks that failed to fix the problem. Now they trying to hide their failure with lie looking for another quick pay based on lies and deciet!!!!
