BAD CUSTOMERS SERVICE, *******

I engaged Govender's for an quote for a new patio door. Govender's sent through an installer. I paid him a deposit for the material and for installation to be carried out in the next week. I took off work on 3 occasions for the installation. The installer never showed up on 2 occasions. I then called and emailed Govender's. I communicated the issue with with Shenaaz and Denisha. On the 3rd installation date the installer arrived late with half the materials no glass on the doors and insisted on me paying him more than the quoted price before he can start any installation. I communicated this to Govender's and the response was that they can come out to assess the material, supply me with a new quote and a callout fee of R500 will be applicable. I am now sitting with half the materials, R5500.00 out of pocket for deposit and on top of this Govender's want to charge me a callout fee and a new quote. Am I been helped here or been **********. This is definitely not customer service but just a means of making a quick buck from an unfortunately situation caused by their own installer
