Shoddy work by Wetility staff

Be careful. They promise you a lot, but deliver bad work. Firstly it took over 2 weeks to get them to get the city to approve my application. They blamed computer error and city. City says nothing wrong their side. Next the installation. They dont really clean up after themselves. They drilled incorrect holes in my wall only to plaster it over. Bent my ibr roof panel, did some weird sealer thing job, just looked totally ****. Then when you try ask why such back work etc, how to fix etc, no real response. So by now, there is no love lost between them and myself. So I suggested, why not give me some compensation? maybe a month off etc. But they just dont respond with an answer. They keep passing the buck to someone else. NOt very good customer service once you have the installation done.
