Major issues with delivery which company is unwilling to compensate

Disappointed by this company. We ordered a wall map for our sons birthday. Delivery was supposed to be up to 8 weeks max, but usually just a couple of weeks. We placed the order on 7 Feb. We received notification that the parcel was with our local shipping company. Needless to say the parcel never arrived. I contacted thee company several times, and they assured me it was on the way. Now, after more than 9 weeks, we contacted them again and they sent the following response:

"Good day. We apologize for the inconvenience but it looks the like your package was sent back to our warehouse by the courier. This usually happens when the address sticker has torn or been damaged from rain and the shipping address can't be determined accurately. We'd love to send you a replacement!"

We rep**** to say that we would like our product to be delivered, but as soon as possible. They went on to say that they cannot get it to us any faster! So because of their mistake, we would have to wait 2 months again!? This is such a disappointment.

I would really expect better from a company that is serious about delivering good customer service. When you've made a mistake: FIX IT!!!
