poor customer service

My husband Boysie Msomi placed an order for X-Guard Matt TC Broze, fully framed trellis door and clear vision Guard with Xpanda. we have two separate invoices for this order reason being we had to make some changes with regards to the security gates that must be installed in the front because of the Boby Corporate rules. The innial invoice is dated 20-11-2017 and the second invoice is dated 05-12-2017 now my focus is on the second invoice the clear vision guard. we have since been waiting for delivery of service since the 05-12-2017 , my husband sent few emails to follow up and the company kept on telling him they will call him when they are ready. i then took an initiative and made a follow up call to LEON the gentleman that my husband had been dealing with, I called and spoke to him on the 19th of December first he proposed to come do the job on that Friday 22nd Dec 2017 which I explained to him that it will not be possible because we going away for that Christmas weekend he then promised his guys will come and do the job on that very same day which was the 19th of Dec. I was at work, my husband cancelled all her appointments to accommodate these guys and no one came and no one even called to say they could not make it. I then took my time again and called Leon that afternoon, which he said he was not aware that the guys did not come and said i should give him few minutes he needed to call and find out why they did not attend to our request, few minutes later he called back and said "sorry Mam we could not do it today we can only do it on Friday" no further explanation as to why, from his side and mind you he did not even call back I had to call him again to even get that response. my response to him was "but i did say we are going away on Friday so how are you gonna do this" Leon said " unfortunately we can only do it on Friday" just like that and i so upset and told him we will expect his guys at 9am Friday. i then sent him an email requesting for his manager's contact details, he read the email but did not bother to respond. So on Friday now the 22nd they called my husband it was just after 9am , my husband was like 5 minutes away from our house he asked them to wait for him. 5 minutes later when he called back the number was on voicemail. Till today we are still waiting for their service. i am very upset and dissapointed by the way we have been treated by this service provider . I decided to write to hello Peter because the guy that we have been dealing with would not provide me with the manager or the business owner's details.
