Terrible customer service

Terribly disappointed with the service received from Mr Price. I placed an order on the 9th October for click + collect. When placing the order it indicated the order will be delivered by the 17th October. Till today I have not received my order and my order does not even reflect on my app profile! I called the call centre on the 17th October and was told my order was to be delivered at the store Friday morning (18 October), but it was not delivered. I called the call centre again on Monday, 21 October, and was told to hold on while they check my order. After holding on for over 15 minutes, no one got back to me. I called the call centre again on Tuesday; 22 October, and was advised they are following up with the courier company and will get back to me. Over 24 hours later, still no feedback was received. I called the call centre again on Wednesday, 23 October, to which they made me hold on again, and thereafter the lady said something to me, her line was terrible, and when indicated to her that I cannot hear her clearly she cut the call. This is absolute terrible service! Mr Proce should not promise dates for delivery if they can not keep to their promises and as for their call centre staff, they should be trained on customer service as they clearly lack that! I am terribly disappointed with the service I received!
