Leon - Cerfontaine Group Landscapers dishonest owner and substandard work

In the first week of January 2020, Leon ***ner ) quoted me on landscaping and a steel fence. The projected period for completion of the project was 3 days. It took 4 weeks before completion. On the day of completion, Leon demanded settlement of his account. It soon became clear he has no experience whatsoever of steelwork, as the steel was rusted after a shower of rain. After numerous attempts to rectify, Leon removed the steel frames from site with a promise to return it after fixing and repainting the entire fence. It is 2 months later and he still has not been back with the promised goods, nor does he reply on my messages
