Daylight ******* and poor service

Enquired with them via whatsapp to inspect my tumble dryer on 18 July 2024. Two technicians came out and ran a full diagnostic and I stood there watching them check everything because I wanted to ensure that it was fixed - they advised that the office would get back to me. I get the quote for PC Board Supply and installation and instead of paying 50% - I paid 80% as deposit - clearly making a big mistake. 1 Technician came out - fit the board and guess what - it didn't work! He proceeded to ask me if i was sure if the plugs where working and had me fetch a lead to check - I have a very recent CoC so I know that EVERYTHING is working - Follow up via whatsapp on Monday and get "it's likely the display board' - ask what happens next - Waiting for supplier to get back to us. Ask what happens if that doesn't work either - then get told there's probably something else going one - today no answer to calls, whatsapp messages - Disgusted is an understatement. You're sitting with my money and the PC Board and now no reply - *******!!!!!!!!!!!!!!!!!!
