MY ONLINE SHOPPING EXPERIENCE

MY ONLINE SHOPPING NIGHTMARE! I purchased a lounge suite on 28 November 2019 and have not received it to date. After like 60 phone calls I managed to get delivery on 14 November 2019. The 3 seater couch was slashed right in the middle and the delivery guys returned it to the warehouse. I received a call for delivery asking for availability, however I have still not received my lounge suite. I cannot get hold of anyone on all the telephone numbers that I have including the call centre. I have even sent an email to the executive PA and even she did not respond. I do not know what to do. I can't even ask for a refund because there is no one answering my calls. The Russels group advertises on national television " SAME DAY DELIVERY "! It's now over a month that I didn't get my lounge suite which was paid for in full. Can anyone advise me what to do please.
