Reliable Store not so reliable

I ordered a set of keys from Reliable store on 6 Feb 2021. I promptly received an email stating that I will receive my product within 16 business days and that I will receive a tracking number. I requested them to send me the promissed tracking number on the 12th and again on the 16th. On the 17th I received an email with delivery dates and on the 18th another email with new dates and it stated I will receive my goods by the 4th of March.. On 23 Feb I received an email stating that the product was received at their warehouse and will be despatched to me soon. On 26 Feb I received an email with my tracking number and it showed that the product will be delivered on the 3rd of March. On the 5th of March I contacted them again and was told that they are waiting for the courier guy to pick up the parcel. On the 17th of March I saw that the company doing the transport indicated that the product was delivered at the client. I contacted Reliable store and ask about it and they told me that that the package was still on its way and will be at their ware house on the 27th of March and will then be despatched and that I will receive a new tracking number. This is their last message to me on the 27th of March, "Hope this email finds you well. We do apologies for the inconvenience caused to you. Your parcel is only arriving on Sunday in our warehouse and we will start dispatch on Monday. This is all because we received a really big shipment and batches were separated making they way to our warehouse bit by bit. As soon as it arrives at our warehouse dispatch will take place immediately. Thank you for your patience." Since then no email was answered and even on their telephone line, after listening to a poor recording telling me that I will be put through to the next consultant after holding for 10 minutes the message just changes to "the extension you are trying to reach is not available at the moment please leave a message. "Worst is you can only phone between 9 and 12 on weekdays.
