North South Plumbing

I would love to give this business a 5 star rating...on their first visit they unclogged 2 toilets, two showers, 1 sink and the price was great....Called them for another job and was over charged for the time recorded. The error was promptly rectified. Called them again for another job but 2 days later the work began to leak....I was forced to call a different plumber to solve that issue.....I wasn't upset about this and I've been waiting for the invoice, and have tried to reach out for another job on behalf of my elderly neighbor who needs plumbing work but have gotten a cold shoulder from north south....this is really confusing...so I'm left thinking that they have internal communication problems. This is disappointing and frustrating because they are good plumbers.....
