Unfinished business transaction

On Monday 27 April I was at the store and was assisted by Lorenzo,I asked if the order can be delivered same day then he said no ,I advised that I will I would be working the next day ,he then said the delivery would be done on Friday 01 May ,the courier guy called me Wednesday 5:38 pm to deliver the parcel,I was on my way from work ,shocked as I was they asked for delivery fee ,I sent them cash send ....they then said they couldn't assemble the package because they have a lot of deliveries and they would some other time I questioned this especially because they wanted they delivery money This is such an inconvenience because now I can't go anywhere because I don't know when these guys will be coming back and if they will even be coming back I'm truly unhappy about the service because I feel I paid for the goods now the business is not following through The process doesn't make sense and is such a big inconvenience to me as a customer I really want to continue to supporting this business but I'm truly unsatisfied
