MTN Online store not assisting.

On the 5th this month I contacted MTN Online store with a query regarding an online shop offer (Ticket#: ********** 0). There is no contact number that I can phone. I waited a while and then resubmitted a new ticket as I had not recieved assistance yet. (Ticket#: ********** 7) Please note this is almost a week later. It is clear no one is going to contact me for assistance. What is the use of these online services if they are not monitored?
