I can confirm I received an email responce within the 24 hours that I had specified -woo-hoo! My celibration was short lived however, as the email they sent was nothing more than a confirmation that they had received my email.
I hoped the following message would help focus their mind:
Dear Sir/madam
I have yet to receive a response to the points raised in my earlier email.
I have had considerable experience dealing with your organisation and can honestly say that I am not surprised at your inability to provide an adequate response within the time frame provided.
I would appreciate it if you could address this matter as soon as possible.
Yours sincerely
Jennifer
