Hillcrest Plumbing & Heating Ltd

Called for a price to replace a hot water tank and authorized them to do it for $850 - and they must call me for any additional charges. Got the bill for $1200 and their office staff advised after the fact that they needed to replace an additional part and charged me for it and to get it from their van. Asked why they didn't call as required and they had no answer. Their only response was that they refuse to do the job without it. Really unfair as that should've been quoted and they were required to get my permission first - not do it and bill me afterwards. Have read other reviews about this company's shady practices.
