Wrong delivery and failure to contact me to rectify

I have contacted RAM service center on Friday the 8th of June to query a parcel the tracking said was delivered and signed for. I was contacted by RAM Bloemfontein the same day, and they informed me they will contact the driver and find out where and with whom it was delivered, and rectify it. I have received no feedback. As the person who signed for the parcel is not a employee of the company listed on delivery address.

I phoned again today, the 14th of June, where I was informed that they will ask the Bloemfontein branch again to contact me. I told the lady that I want that parcel delivered to me TODAY.

I have yet not received a phone call nor my parcel.

This is absolutely poor service! Unacceptable!
