relentless phone calls made to incorrect number for a Mr S Ntuli

Our company phone - number 083 *** ***x is being inundated with calls for a person by the name of Mr S Ntuli. We are receiving calls daily for an amount of R72,50. We have requested on several occasions that our number be removed as this is a waste of our time and negatively impacting our business as our lines are being held up with these ridiculous calls. I would hope that the Foschini Group has some sense not to call a number if the number is incorrect? I have tried all routes, talking to the consultant has not worked, and asking for our number to be removed has not worked.... what else must we now do?

We have had enough of this, and this is now bordering on harassment. We respectfully request that 083 *** ***x, not be dialled as this is a place of business and there is no and has never been any person by the name of Mr S Ntuli here.
