If the harrassment calls are not stopping, your last choice might be getting a new number! It may annoying to change your number, but its a fast and guaranteed solution. This may, apart from the silence of the phone, even have advantages. For one, you may find providers with even better prices and services. As competition is fierce companies will offer interesting incentives to persuade you to buy their product. Mind the fine print – Some providers hide additional costs!
Of course, once you have a new number to share it with your friends and family again may be annoying but at the end og the day worth your while. Look at it that you will not dislcose it to anyone whom do not know or trust. Furthermore, have closer look at the companies you share your number with. For instance, providing your number to an insurance quotation service may result in calles from insurance brokers. Remember, once in a telemarketer’s pool of phone numbers there is no way to escape.
A fact to consider is the aquisition of two phones. One for private use and one solely for anything else like online quotation services. The latter would be perfectly suitable for prepaid phones – since you only use it to receive calls you will hav no additional costs to endure.
