Spec Savers Bad online service

I placed an online order on the 11th Jan. The confirmation email received same day and few days later I haven't received any update about the status of my order. The website says delivery will take 7 Woking days, now on 16th Jan I sent an email to ask about my order, I'm reminded of the process of 7 business days and that I will receive an update. Told not to worry as the delivery to the collection store is also included in that 7 business days. This morning again I'm the one sending an email to ask since we're now on day 5 of the 7 business days, still no response from your side, not even that automated response. All I want is to get my contact lenses by this Friday as it would be the 7th business day. I really didn't expect such kind of service from you, one would think ordering online is the best and quickest way, but this is just too frustrating as you lie that you will update me but I have to be the one sending you emails to enquire about the status of my order.
