Infuriating phone calls

For the past month I have been receiving Infinite calls from African Bank call centre agents during work hours. I find this really annoying, when I have told the 1st consultant not to call me during work hours(Requesting all recorded calls made to my cell-*** & work ***). Absurdly they call on my cell phone 1st & then on my work phone even though I have requested that they call me after 5.I have also requested for them to send me every single signed page of my loan contracts and I still haven't received anything yet ,I cannot be taking calls like this during my work hours, this will result in me having to sign warnings & eventually being fired from my job. YES ,they are only doing their job, but I should be respected enough to do mine without feeling that I am being harassed by voluminous calls during the day. It stops today.1 phone call per week will be allowed on a Saturday just after 9.Any phone calls outside of this request will be ignored.<br> But please speed up the process of my request-as mentioned above(signed copies of my loan contracts).<br> PS.I had to request for permission to use the internet for personal use ,during my work hours to send this complaint.
