Mr Price online orders

I bought clothes online as a gift for my son and when he received the parcel, the order was incomplete. I alerted the customer care department and they directed him to the local outlet to pick up the replacement order. When he got there there, the assistant claimed to know nothing about the order and promised to find out what was happening and to get back to him. Needless to say 3 weeks later we are still none the wiser. I have emailed, and sent messages on FB page (calls are just too time consuming with waiting times), all to no avail. So now I have no choice but to place this review and hope this sparks some assistance.
