Disappointing service. Will make sure I Spread the message.

I placed an order for an item online on Wednesday 18/03/2020. I have been trying to call the contact centre for 3 days straight and they refuse to answer. On one call, I held on for 15 minutes straight. I called the Cresta Branch to query if my item had been delivered. The manager stated that the item was incorrectly priced an that they will refund me. Firstly, I only placed the order because of the price indicated on the website. In my opinion, it is regarded as false advertising. I mentioned to the manager that I am upset at this and he said "you can take it up with the online store". This is after I had informed him that I have been trying to call them for the past 3 days. Please may someone from Incredible connection contact me asap.
