I even wonder why I have bought again

Its OFFICIAL, Boardmans online is the worse online retailer. On the 29th of June I placed an order online and according to the order confirmation email delivery was going to be 3 to 5 days . On the 6th of July I sent an email to enquire when the order was going to be delivered and I received a reply saying the order was going to be delivered on the 7th. I then phoned on the 10th to enquire why I had not received the order. The call was taken by a very unprofessional consultant to told me hold whilst she checks. I held on for over 10 mins only for her to say the items I ordered are available and will be delivered next week. She even sounded irritated as if I am fusing for nothing because according to her the order was placed on the 3rd of July. I phoned again on the 14th to enquire but was answered by a consultant who once again put me on hold for over 10mins. Eventually I hang up and sent an email. To my shock I received a reply written nothing in the body of the email. My fear is this is not the 1st time I have had a bad experience with boardmans . It took me over 6 months to get a credit . Now should I wait another 6 months to get a delivery I paid for???
