False advertising | Late delivery | Bad service

I ordered my wedding suit from Topman UK on the 29th of January 2016. My order was promised to be delivered on the 11th of February 2016 in South Africa, but it did not arrive. When contacting Topman to find out why it was not delivered on time, they then informed me that they were not sure why I was promised it would be delivered on the 11th of February (I have an order confirmation to prove this), but all international deliveries are given a 4 week delivery time. <br> I had expressed that this is unacceptable, as this time period falls out of my wedding, which will obviously ruin that plan, and so I would have never ordered the suit from them if I had been aware of the ACTUAL delivery dates. They are being extremely unhelpful in trying to find out where my suit is, saying that they can't track the parcel, and that they cannot track it until the 1st of March 2016, which is almost a month after my promised delivery date.<br> This is false advertising on Topman's behalf, and completely unacceptable. On top of that, it has been bad service. I hope to expect them to resolve this issue before I find myself at my wedding without a suit.
