Send me my pin

Am very disappointed with Mr price i shopped with you guys on black Friday and i won R200 but up to date i have not received the pin was only sent a sms with the withdrawal code but never got the pin i have been trying to get help through your platforms but to no avail i really don't think sending just a sms with a pin can take the whole 3 weeks its either someone is not doing their job or this whole thing was just a ****
