Shocking lack of service

I hired this company end of last year to seal and waterproof my whole roof. It didn't take me long to realize that I still had leaks. Once they finally came out to inspect the damages, by then I had hired another company to replace gutters damaged by the storm, I was shown pictures by the new company that a) the whole rim of my roof was not sealed and had holes in it, which 5 star was supposed to fix as per the quote, paid for. Thus I incurred water damages. and b) the roof hadn't been properly sealed, hence the continues leaks. When informing 5 star their excuse was, they left the roof in that condition cause they knew we would have to replace gutter at a later stage. Thus they unilaterally decided to leave work they had quoted and been paid to fix, so that they can fix it at a later stage . if I used them again. This whole time we were under the impression that as per quote and payment the work was done. This is not acceptable and has caused water damage to the side of my property and the continues unfixed leak in the front has caused a bigger hole in my ceiling. When you contact 5 star they have different excuses every time, ranging from unidentified materials being ordered to the apparent unavailability of staff that were just informing the receptionist about the unavailable materials. I understand that the floods caused many damages to other clients and I have been patient for months awaiting for 5 star to get back to me and fix what they failed to fix originally but the lack of communication and what seems to be dishonest conduct if I read the hello peter reviews will force me to pursue a legal route where I will have to claim for all damages and legal costs incurred and those damages still being incurred. Shameful that clients have to pursue legal action to have their rights protected. Shocking that insurance company like Santam can recommend a company like this, I think someone should inform Santam as well.
