Lack of full diagnosis by technicians, and add on fee for a return visit which did not cure the issue. Long waits in for engineers that turned up over 4 hours late. Costs to me of installing a dehumidifier, and running it for 2 weeks, only to find the engineers had missed a 2nd leaking pipe.....Note...I found the leak!!! Poor customer service response from Michelle Doherty, no opportunity to raise my concern further when Michelle failed to call me back after several messages left , and then said she will respond on Friday, which is what she said last time. Today I was told by Michelle that this conversation is now over when I asked to speak to her superior.
