I wrote this email on 26th August and received a response saying That I would get a reply within two working days - I am still waiting! Dear Sir, I am writing in regard to the callout yesterday to repair my patio door lock assembly. When the technician arrived he removed the entire lock assembly and left with it to return to base to get a replacement and give me a quote. I was extremely surprised as this left me compromised should I not like the quote. When the quote came in at £250 plus installation I was shocked but accepted as he had taken the old lock away. When he came to install the new one it was not a direct replacement so he used a grinder on the frame making a mess. It still didn't fit so he said he would fit the gearbox to the old assembly and it fitted fine. The cost was now £180 still an excessive amount . I paid the full bill of £322 and said goodbye. Looking online I found the same part for an average price of £30, quite a difference. I have already posted a review online but thought it a good idea to write in person so you can help me understand why you are charging so much for parts. I have no issue with the service fee just the price of the gearbox/lock. Please feel free to contact me to discuss.
