Bad service and communication

Placed an order for a Panarottis pizza had a free delivery promo code no response from driver, long response time from Mr delivery customer service. Just an apology and I they let me fight for a new promo code. Nothing about what happened to my initial order just a refund to wallet after making me wait for more than an hour with no proper communication and after heavy continuous prompting on my end. Half begging for a response. All I got was an apology and no explanation. Bad service. Previous complaint unresolved. What is happening with Mr D Food service. I know its holidays but still you guys get paid to do a bad job. I would like this to be taken up a notch to upper management as I feel it was not explained to me in the proper manner and after all my trouble I don’t think I deserved this type of bad service from a company I use often.
