Bad service

On the 13 September 2018 I purchased items online from Edgars. The items were supposed to be delivered in 5 working days and I been waiting ever since. Whenever I made phone I'm given a reference no and told that someone will contact me but it never happened. After numerous calls a lady contacted me and took information that they already have like purchase date etc and she said she was going to get back but she never. I have a feeling that I will be told that the items are no longer available and since they were on sale they'll re advertise and I will have to pay normal price.
