Unprofessional and ********* company

Terrible experience from this company, selling defective items and then blaming you for using the showers incorrectly even though they said the showers came with a 1 year warranty. Bought 4 instant heat showers in March 2024, 2 months later an element burnt out and in December the shower gave up completely from that same shower, waited 5 days for feedback and then they say its negligence and won't replace. Bare in mind, i had all 4 installed at same time by a professional electrician and its only the one thats having the issues. Will never buy or refer them to anyone
