Annoying Calls

If it were possible to continue without ticking a star I would not have ticked any, what's this never ending calls. DSTV stop dishing out my contact details for external marketing 1.these consultants are rude 2.i know who to call if I need info 3.if it's not for decoder warranty it's for DATA 4.i am employed and productivity is my priority rather than being constantly getting unnecessary disturbances from your telesales consultants. How can 7 people be calling one person to offer the same service?
