Worst online experience

I ordered items online 2-3 weeks ago, understanding fully there would be a delay on delivery with the lockdown. However my item is out on delivery for a week now and have not receive any form of communication back on my emails etc. If I call mrp home. I get inconclusive and snotty remarks. If they could just give you a date or time or atleast reply to your emails that would be great for planning!!! Very frustrated!!!
