Unprofessional and lying to cover up

As a long-standing Nedbank client, I've never had a problem with their outsourced contractors for my burst geyser claims over the years. When they told me Great South Contractors was going to install a new sink unit and repair my damaged wooden floor after the hot water pipe in my kitchen burst, I was hoping for the same standard of service as their other contractors. Great South's contact person gave me a morning call on the second day after the pipe burst to say that an assessor would visit at 11am to check the damage, then hurried me off the call. No assessor arrived, and no one called to explain the person's absence. After a silence of more than 24 hours, I called Nedbank. They said they would inquire and reverted to me to say that the contact person had said the assessor didn't arrive because I had said I would call back about the visit and she was awaiting my call. What a bare-faced lie! I did no such thing. I immediately told Nedbank to switch contractors because I didn't want to deal with a company whose assessor didn't arrive, lacked the professional courtesy to make a follow-up call, **** and blamed me to cover up. If this was the introduction to Great South, I didn't want to deal with them. I'm so glad I switched contractors because the new company was prompt, professional and worked to a high standard, which was the opposite of my experience with Great South Contractors.
