Campaign support team not responding

Good Day. I have purchased a product during your promotional period i.e. I qualified for the buy and get promotion. I have been attempting for the last few weeks to contact the *** number to redeem the incentive. The following has been my experience thus far. <br> 1) contact centre number is always busy and holding time is in excess of 15 min (before I drop the call) <br> 2) the IVR transfer you to a conference facility, where you are directed into an additional queue<br> 3) I cannot get hold of an agent to redeem my incentive <br> <br> Regards<br> Bradley
