No service yet again from Maxidor

After having to contact Maxidor yet again who promised to reinstall my burglar bars between 11th and 15 Jan which they failed to do and then promising to contact the Cape Town branch on the following Monday which they failed to do, I had to call in at the Cape Town branch myself to discover the manager knew nothing about my problem. I explained to him what had to be done. Lo and behold they arrive to install 3 burglar bars that had already been installed. I was told that equipment that was needed would have to come form Joburg. I complained yet again to management .There was no response. Instead an apology came from a lower ranked staff member as top management appeared to not care. In the meantime vendors needing to install blinds and a window must be asked again to wait while Maxidor fumbles along.NO COMMUNICATION
