Cell C Sales Harassment

This people phone me 4 times in a row, every time I answer I am on hold, there is nobody on the other end. I put the phone down, they phone back immediately. FOUR TIMES IN A ROW, are you crazy? How do you phone me and then when I answer you put me on hold, bro, you called me, why the hell am I on hold when I answer. Stop fkcing doing this, it's annoying. If you gonna call me, speak to me, and tell me *** you want, don't have me on hold.
