Still waiting for sim card

I ordered an LTE router on the 20th of November 2017. The deal was a free month of data and then payment for 11 months then the LTE router is for free.

I received the router a few weeks later, however the sim card with the data was not delivered.

I then logged a call with Mweb to say that I did not receive my sim card. They scheduled delivery again and the courier said they can deliver on the 5th of January 2018.

I agreed to this and gave them my home address as I will not be at work on 5 Jan 18. Then the day after scheduling I receive a call saying delivery will take place today. I rush home to be at my home address from work, give the courier a call that I am available for him to do the delivery but he said he can only do the delivery the next day at my work address. Not wanting to create waves I said it is fine. The next day I receive an sms saying I was unavailable for delivery, so my sim card is being sent back to Mweb and I should contact them. This is extremely frustrating and feels like Mweb does not have any control over the courier company they use and I do not feel this is customer service at all.

On top of this is the fact that Mweb is scheduling my first debit order for 7th of Jan 2018 without even receiving the sim. (How am I supposed to use this?) So much for the free month!

When I phoned Mweb again yesterday, the response was merely that I should receive the sim card soon. Just did not sound like they even knew how to help.

I am at the point where I just want to block the debit order and cancel the deal (due to no delivery of the product) as I feel waiting two months for a data deal is simply not acceptable and does not reflect any customer service in the slightest.
