Shocking Service from Mr Price Home

We placed and order for x2 office desks, x3 office chairs and x1 shelving unit online through the Mr Price home website. All items were listed as "in stock" on their site. We made payment and received confirmation that our order was accepted. A few days later i received an e-mail from Mr Price home that the shelving unit was out of stock and we can expect a refund within the next 5-7 working days. 2 weeks past and still no delivery or e-mail from Mr Price Home regarding the expected delivery date. We had to call into the call center to find out where our order was. Only to be told by the call center agent that Mr Price Home is in the process of changing warehouses - thus causing a backlog with their deliveries as they have to use a courier company to make the deliveries. We accepted this excuse this time around and decided to wait to hear from the courier Company. About a week later i received a call from the courier Company notifying me that delivery will take place today 28/09/2017 between 09:00 - 14:00. Delivery happened when they said it would. But to our disappointment they only delivered 1 office chair. Did i receive a call from Mr Price Home? NO! Did i receive an email from them explaining where the rest of my order was? NO! Again, i was forced to call into the call center. The call centre agent informed me that they were out of stock with the office desks that we ordered. Could someone from Mr Price Home not take the initiative to pick up the phone or send me an e-mail notifying me of this!!!???? NO! They will gladly accept your payment, but will not bother to communicate with you unless you call into the call center yourself. Why are you allowing customers to place orders for stock that is no longer available!!?? And why the lack of communication!? Your service is and has been utterly ridiculous! This has been a huge inconvenience for us and will be taking our business elsewhere.
