Delayed delivery and no service

My husband bought building material on Saturday 21 March 2020. The reason we went to this store is because we once had a good experience, however this time we are receiving no service at all. The material had to be used on Monday and he requested for delivery to be made as soon as possible. They promised they will deliver before the 25th March 2020. Monday 23 March 2020 we called making follow up on the delivery out of frustration as our project is on hold because of the material. We were told that the material will be delivered today 24 March 2020. In mid day today 24 March 2020 we called again and we were told that the material will be delivered today. After 2 hours we decided to call again only to be assisted by a rude salesman who said the delivery will be made the following day of which is 2 stories from 2 different sales man at the same day. I'm asking myself if we have to be treated this way as if we bought material on credit. Even if one bought by credit service should be given according to the requisition. If only we knew this would have happened we would have taken our money else where surely we wouldn't have to wait for material to be delivered for over 3 days.
