Unprofessional service from Anne they dont deliver, a waste of time

Buildit Bedfordview is so unprofessional. I ordered a plaster sand on the 19th January 2022 in the morning to be delivered in the morning of the 20th January 2022. The staff member assured me that the sand pit will be delivered in the morning of the 20th January 2022 provided that I send them proof of payment and the payment is cleared immediately. Immediate payment was made. The material is still not delivered as I am writing this complain. I called buildit Bedfordview and they said Anne is the only one who can assist me who deals with deliveries and they do not know where she is. For the past four hours they took my number and said Anne will call me to let me know how far my order is from delivery. All the staff members can't assist me because they can't get hold of Anne. I can't speak to anyone for that matter even if I am asking to speak to a supervisor or manager they tell me Anne doesn't have those. I could have ordered from your competitors but I chose your store because I thought you will give a service but no I was wrong. this is pathetic. I want my refund so I can go order somewhere else. The project is on stand still because of your unprofessionalism. The biggest mistake of our lives was buying from your store.
