Extremely bad customer service from store manager

I ordered two parcels to be delivered at Ackermans Mamelodi Crossing, today around 1 I went there to collect my parcels, the lady who assisted we took my ID Card and went to fetch my parcels, it took them time to find my parcel but I got it . I arrived home unpacked my parcels only to find out one parcel its not mine, I was given an incorrect parcel mind you I take a taxi to go that complex. I tried calling them numerous time with no luck then I went back again to return this wrong parcel and collect my other parcel which the should have checked in the 1st place that I received correct packages. When I got there I spoke to the manager I told him they need to reimburse me for fhe R30 I spend for their *********** service. Why in the first place such things happen, why dont they check customers parcels and make sure we get correct one. Why does it has to be on my expense that they messed up. Now I am at the store as we speak I arrived here at 15H15 now its 16H08 and he has disappeared on me, he told me he needed to make a call and he will give me feedback. How can a whole manger behave like this treating a loyal customer like trash, why doesn't he feel the need to be sincere about this whole mess his staff created. I am so heartbroken because I regularly shop at this particular store and built such an amazing relationship with his staff. Why should I be treated like this, even now his no where to be found, one of the staff members told me he left the store. Wow this tops it all I truly cant believe such behavior exist especially coming from a manager, how the hell is he going to lead when he himself his rotten.
