Mgtv poor service and lying staff

I ordere dstv explora with installation. I have already booked my installation on Thursday 31 May 2018 for Saturday 2nd June 2018. No one ever came. When I eventually got hold of someone past 18h00 in the evening I was told that the installers was drunk on duty. This is very inconvenient as I will not be available the next day and I work during the week. The ladies in officehave been promising me the whole day that they are on their way. They have been lying! They were well aware of the situation and blatantly ****. The seevice from that place is horrible and unacceptable. They should not be a accredited dealer and be removed as a service provider. It is the worst service ever that I experienced in my life. Now I would like to know what they will be doing to assist me as the client. Otherwise dstv can take their service and shove it with it's poor accredited service providers. A service that is supposed to assist me as the client whohas consumer rights. They really have a poorservice.
