Non-delivery and no feedback

The salesperson, Wasim, has been extremely helpful and friendly both times I dealt with him, last week and today. This review , however, is not about him but about some of his colleagues who are letting him down by letting customers down. A shower was supposed to be delivered yesterday; it was not. Today Wasim was promised by his colleagues that it would be delivered today. I phoned CTM eventually and spoke to two different people, one of whom promised to phone me back. She has not. No one has contacted me to arrange delivery and I have explained more than once that I will be travelling from tomorrow. Why can CTM not deliver an item bought a week ago? CTM is holding up work by one of the other companies in the group by failing to deliver. That means, that company is not getting paid either because the work is not being done.
