Poor communication on order, multiple excuses.

I placed an order for an LTE upgrade on my existing ADSL line on Thursday 12 October 2017. The sales agent told me about the prompt delivery after an ITC check of the sim and router, even going as far as telling me that it would be as soon as the following day. Upon contacting MWEB this morning, I am told that Digital Planet have no stock of the sim card required, upon calling Digital Planet I am told that the LTE routers are in fact out of stock. Digital Planet ensure me that they will receive stock this week, whilst MWEB tell me that it could take up to 2 weeks. Where is the communication???? I am running a business with an ADSL line that is not working correctly, and was banking on the "prompt" delivery as promised!! No alternate arrangements or contingencies were offered by any party in light of my dilemma - I am simply told I will receive an when THEY are ready to deliver. Awful customer service!!
