Stop harassing my colleagues on her number for an account that is up to date

I am home choice customer and my account is up to date but they keep on calling my colleagues number where as I am not getting calls from them. I have contacted the call center and requested my colleague number to be removed which is ********** 725 Diana. This number need to be removed as I have never gave you this number as next of kin, we do not have relationship with this colleague but you keep on requesting me to her. I have placed an order first week of July and still not being delivered. My order number was #0 and still not even an sms confirming the order. Please stop harassing my colleague with your calls , I have given you an alternative number if you cant reach me, which is not the case because you are not calling me.
