Bad service delivery promisses

We Purchased goods displayed on a special from Musica Middelburg Mall on the 06/06/2019, but could not receive the goods due to no availabilty, we were promised that the goods will be ready for collection on the 10/062019 and they will phone us for collection, resson for collection on the 10/06/2019 was due to the fact that they will order it from Musica Ilanga Mall, situated in Nelspruit. Nobody contacted us, we then visited the store on the 10/06/2019, where they informed us they are still waiting, and again said they will contact us, again nothing happened, we contacted them again on the 14/06/2019, with the same answer, no goods yet, and will contact us in a short while they just quickly wanted to follw up. Three hours later still nothing. Then we contacted the Area Manager, who apologized and said she dont know anything about the problem, want to do a quick follow up and get back to us, which she did, she told us the parcel is on the way, and should be ready for collection in a short while and that the specific business unit will contact us soon for delivery. After approximately one hour, the shop phoned and said the parcel is delivered but our specific ordered goods was not included, and will now only be available for collection on the 19/06/2019. This is unacceptable, as we needed the parcel, before latest the 15/06/2019, due to the fact that my so leaves Middelburg on the 16/06/2019 where he will departure to Cape Town. This is totally unacceptable especially for such a big chain store, I am sure there was alternative arrangements that could have been made in 8-9 days!!!
