Generally, we advise extreme caution regarding any business making unsolicited calls/emails/SMS, not least because there may be Data Protection law breaches involved -i.e., that they may have obtained and /or are using your data illegally.
If there are companies who approach you in this manner that you would like to consider using please do check them first on our website https://timesharebusinesscheck.org/checking-and-decision-making-section/ or direct with us BEFORE signing contracts or paying any monies.
Please note while we endeavour to keep this site as up to date as possible, there are new companies forming every day which may not have been brought to our attention as yet.
We would be unable to advise by which methods your details have been obtained but you may wish to contact your telephone service provider to ask what call barring options they may have available to you.
You could also report the unwanted contact to the Information Commissioners Office (ICO): https://ico.org.uk/make-a-complaint/nuisance-calls-and-messages/
We advise registering your details for free with the Telephone Preference Service (TPS): http://www.tpsonline.org.uk/tps/index.html to reduce unwanted calls.
