Bad service and poor customer care

On the (20/06/2025) I ordered 3 Items from Phat Galz Boutique Order #40720. To my surprise, only 2 items were delivered, item 6727 and item 6733. My 3rd item 6694 was not delivered. On the 2025/06/23 I sent them an email to enquire about my 3rd item and they responded on the 24 Jun 2025, and I was told they are still waiting for this dress, however I can make a replacement for dresses that available. On the 28 Jun 2025, I sent another email with two other dresses from their online store and requested that they replace my order with one of those dresses, to date I did not receive any feedback. I followed up with another email on the 2 July 2025, still no reply. Mind you the same enquiries on email, I was also making them on their WhatsApp number, but still no response. I have requested for a refund via their WhatsApp number on the 7 July 2025 and they responded that they will fix this and they are sorry for the inconvenience with my order. Today on 8 July 2025, I sent them another dress to replace with or refund me my money and they said they will request for it. Every time I try to call their WhatsApp number, they hung-up and say they will call me back but they never return my call. I think I have tried from my side to get assistance from these people and I am left with no choice but to lodge a complaint with the Consumer Protection Ombudsman. It seems all this bad publicity from Hello Peter is not working, already there are 42 unhappy customers, not even a single 5 star review from a happy customer, because they are not changing their behavior. Why accept an order of an item that is out of stock. If supporting black business means being frustrated like this, akuyekwe.
