Very pleased with our doors but after sales service very poor. After installation tried to register for 20 year guarantee on line but couldn't do this as the site was being updated due to Data Protection. Advised to try on the 2nd July. Phoned Customer Services to try to register the doors this way, only to be told it couldn't be done because of the system update. The person I spoke to didn't offer to keep the details on file and register them as soon as possible, just said to try again at beginning of July. On the 2nd July managed to register and had the message 'Thank you, we will contact you'. On the 16th July received a message 'Registration complete, you will shortly receive your Welcome Pack and Certificate'. Nothing has been received which is worrying.
