Mr Price Group / MRP review: Online order

I placed my order on the 13th December. The Mr Price app stated due for delivery on the 23rd December. The status on the order tracking has not updated since the 15/12. Called the contact centre where the advior said it takes 3-5 working dayds for delivery. Today is the 5th working day. She then changed it to say its 5-7 working days. This is seriously not on. Im sure shes just making things up now. These a gifts and I gave ample time for delivery. What if the stores are closed for collection tomorrow! I am extremely disappointed anf want this taken further.
