Edgars online order fail

I have ordered online from Edgars on the 3rd Of June. on the 7th I noted on my online account that it was in transit. I called on Tuesday the 11 June to enquire as to when my order will be delivered from the online team case number: ********** 3283/GO and was told that it should have been delivered on Friday to which I rep**** it was still in transit as per online profile, it was escalated. Tuesday I called again reference ********** 1033/GO and was told that it will be delivered later that day. This has continued and I was also called back and they enquired as to if it was delivered, On Thursday I noted that my ordered stated completed and when I called I was told not to be concerned it was probably just delayed but it will be delivered that day. I called again at night and told again that it will be delivered in the morning. This morning I called and through all of this they would not give me the courier company name or address. the online states MOGALIADI SHIPMENT# ********** 52. I then spoke to a lady, Joyce who told me that the order, as per couriers, has been delivered and signed for. This was said as the last resort after telling me constantly that it was going to be delivered shortly. I have not received or signed for anything and still waiting and concerned as I have been constantly misled and now told that my order was delivered and signed for. I asked to the proof of signature and then told further investigation will be needed as they have not seen the delivery note. I have ordered from Edgars online many times before and always received excellent service form the previous couriers, Dawn Wing and this is the first time I have had such problems. I am very upset and have requested that this be resolved as soon as possible and my order to be delivered or retrieved or replaced immediately
