Edgars service delivery a complete joke

So... another 3 weeks later and still no wris****ch. I've been back to the store twice. Yesterday's excuse takes the cake! This time I was told that the delivery people brought the package to the watch counter and was informed that he needed to book it in by the manager. Upon later enquiry the manager said nothing was delivered to them. Enquiring from the supplier/courier it came to light that the delivery guy walked out the store without delivering the packages and that they will now post the package to Edgars for delivery between Wednesday (yesterday) and Friday (tomorrow). When I asked when the watch was delivered the reply was Wednesday...yesterday WAS Wednesday. Then it suddenly became Tuesday and then Monday... I am sorry, but I cannot find anything more to do about this situation than shake my head in disbelief. This is laughable, but in no means funny at all. What is Edgars going to do to finally sort this out and what are they going to offer to make up for this dreadful service? Almost 3 and a half months to replace a broken glass on a wris****ch and so much of my time wasted....
