1. Misdescription of item - I initially used their contact form to explain an item purchased was not compatible with our heating system and that this limitation was not noted anywhere on the website. I asked for an exchange. This was completely ignored. 2. Breach of contract - I was then unreasonably refused a return within policy due to a fault with QS supplies communication system. They simply said it was now outside the 14 day policy so would not be honoured yet it was because they had not responded. 3. Poor service - unhelpful emails received demonstrating my query is clearly not being listened to properly or being escalated as requested. This is in addition to the contact form not working and the company making no effort to resolve this when it has been reported.
