Hi, thank you for your question, I will assist you with this.

Essentially you can sue the company for harassment in a civil action under the Protection From Harassment Act 1997 seeking an injunction against the company and damages. However, they could try and defend any claim depending upon the circumstances and the reasons for the call.

You would also have to show that the actions of the call centre caused you damage, either financially or personally or both.

I would suggest you review the legislation to consider your options. Here is the link to the Act - http://www.legislation.gov.uk/ukpga/1997/40/contents

Depending on the circumstances and value of the claim you may be able to seek assistance with this from a solicitor who may act on a CFA or no win, no fee basis. Alternatively, you could commence legal proceedings yourself. I would advise the use of legal representation in a case against a large commercial organisation.

Here is a case of a woman who sued British Gas for harassment - interesting article for you to consider - http://www.out-law.com/page-9826
