No Delivery

On 08/04/2019 I placed an order, paid for it and received confirmation from Truworths that it will be delivered in 3-5 working days. It is now 24/04/2019 and I have not yet received my order. I phoned on 12/04/2018 and requested delivery date and I was told delivery would be that same day. I sent an email on 17/04/2019 to which I have received no response. I also phoned on 17/04/2019 where I was again told delivery would be that day. I phoned again on 18/04/2019 where I was AGAIN assured delivery would be that day. I phoned again on 23/04/2019 where I was YET AGAIN promised delivery even if it meant after hours delivery. I received a follow up call this morning and to your consultants surprise I have still not received my parcel. It is now 9;25 and I have heard NOTHING. This is nothing other than THEFT. You took my money and agreement as per your confirmation is 3-5 working days. Should I open a case against you TRUWORTHS? Blaming courier company is not an excuse as I purchased the clothes from Truworths and delivery is YOUR RESPONSIBILITY. I demand answers!!!!!!
