Bad Service

So on the 19th I buy something on the app and it gives me a option for delivery the following day, this comes at a cost I must say which I was happy to pay to receive the goods the following day. The parcel does not arrive as expected and the pass (the day which I paid for already) the following the now the 21st I go to their office to find out what is the problem, I get to the front desk and I get asked the order number and they check on the system to confirm that the goods are here then later they say I should wait for the manager. The manager comes and he tells me the goods has been delivered to a wrong warehouse at this point he is not aware that the front desk has already told me the goods are here. The manager says i should wait the delivery will be done on a Friday which is now 4 days after the paid delivery date. I then ask them the goods are here why can I not be given them he says the order will have to be canceled and only after the process which could take a week os completed the money will be credited to me. Then I tell them I do not have a problem with that unless it's done while I'm here so that all can well. I mean there is a reason why i paid extra to get the goods on the day it was meant to be there. This is unacceptable and it's a continuous thing because not even anymore bothered to call and inform me what the problem was.
