The customer doesn't matter to @Home

I recently ordered eight bath towels, two hand towels and a number of face cloths that were marked down by 75% on @Home's website, on Tuesday 13/11/2018. On their website all towels that I ordered were marked as 'in stock'. After placing my order and paying for my order I received a confirmation email from @Home soon after, confirming that my order had been placed and the items were being prepped for delivery. On Wednesday 14/11/2018 I received an invoice from @Home which only reflected my hand towels and face cloths that I had ordered, however my ordered bath towels were absent from the invoice. I then had to follow up with @Home on my own accord to find out why there had been the omission; to which I was informed by Donita Bredekamp that @Home had run out of stock of the bath towels, @Home was trying to source stock or they would refund me - had I not contacted them myself, I would never have known! I rep**** querying when stock would arrive and Naveed Siddiqi responded via email to say that @Home would not receive any further stock (items had been over sold!) and they would not be able to fulfill my order. I requested for a manager to contact me directly, twice, it is now 21:45 on 15/11/2018 and I have still not been called. I now receive an email to say that @Home has cancelled my order; a cancellation I did not request nor want. I am appalled at the terrible level of service and lack of ownership on the part of @Home: they should not be advertising items as in stock when they themselves have over sold their items. Nor should I as their customer be made to wait, and feel at ransom, to hear from a manager. To resolve my grievance; I expect to be contact directly by a manager and for @Home to source new towels for me without any increase of price to me.
