Bad service

On the 10th of September I made an online order selected truworths store collection point. Courier called me on the 12 Sep to confirm the delivery address. I went to the store to collect my parcel and i was told that the parcel has been delivered to a certain address not the store. when i called online they told me that the order was delivered at store and they were going to contact me on the 14 Sep up to so far no call has been made by truworths their customer services is poor instead they are busy sending me statement reminding me about my installment but they failed to deliver.
