Take-a-lot overnight shipping is a ****

I am leaving for Durban tomorrow afternoon and placed an order on take-a-lot, last night (Thursday Night). All the items are in Cape Town so overnight shipping was an option. I paid for the order and paid an additional R50 for the overnight. I have a screenshot of the screen that confirms the delivery was to be done today (Friday) and then got the email delivery note to say it will only arrive on Tuesday!

I called the contact centre to explain that I need the items for the weekend and cannot wait till Tuesday as I will not be in town. I even asked if I could go fetch it at the warehouse but they informed me that I would need to wait till Tuesday and the order was not eligible for cancellation or pick-up. I am leaving tomorrow and urgently require the item but sadly the customer service at the warehouse is awful and extremely unhelpful.

It is impossible to speak to a manager or to get a refund so I have to go to a store and buy the items before I leave and arrange for someone to be at my delivery place to pick up the order in my absence which is extremely inconvenient.

All take-a-lot wants to do is refund my overnight shipping money, which I don't want. There was an option for Saturday delivery so I don't understand why I have to wait till Tuesday for an order of items available in the same city I am in.

So ****ed off
