Delivered Half a Can

About two weeks ago i ordered food for delivery from Steers Blue Valley. the food got here promptly however when i took out the one can of soda from the paper bag of which the can was closed it felt light as thou the contents inside was not full. As i turned the can to look at the bottom end it was evident that the soda can was a defect. I called in this incident and i was told by the Tebogo that i would get another can delivered immediately. This was not done. I called the customer care line about this issue and spoke to a Bonnita and yet again this issue in not resolved. Very bad customer retention turn over time. And again the defunct can still sits on my desk awaiting Steers to come and collect it??
