Disappointed by the service

I placed an order on the 15th and submitted all the required. After a lot of following up and getting canned responses to a tracking system that did not exist I finally had Shakeel acknowledging that there was a delay in stock of what I had ordered and I had to change to a different brand. Eventually on the 23rd the item was dispatched but to this day I am still awaiting delivery. The courier company they use has been sitting with my parcel since the 23rd. I am aware of the public holidays but there has not been any movement on working days. Rentoza can't help with that and the courier company is not taking calls.
