Bad customer service

i bought shoes from Zando some time last week. Courier it was supposed to deliver my parcel on Friday 26/01/2018 , due to incorrect number they were unable to deliver and they notified me. today 29/01/2018 at 08:05am I called Courier it, spoke to a black lady, I explained the situation to her, gave her all my details. she said my parcel will be delivered today, I gave her the correct contact number and even confirmed it with her twice.

after lunch time I called in and spoke to a white lady Samantha who promised me that my parcel will be delivered today, but to my surprise she still had the incorrect contact number. I gave her the correct contact number & even confirmed it with her. now at 16: 15 I called her to find out where my parcel is as she promised me that it will be delivered today, she couldn't give me a straight answer. she told me the driver's phone is off.

how can the driver's phone be off if he is out on delivery? how is he going to get hold of the customers? I called her back to find out how possible is this, then she told me I can be angry all I want fact is the driver's phone is off & there is nothing she can do.

this is totally unacceptable, I owned up to my mistake of providing incorrect number but I made sure I called the company as soon as they opened to rectify the mistake & they actually didn't do their own in making sure the driver has the correct number that I gave them.

if I don't get my parcel on time hey will have to refund me my money I paid for the shoes & they will see what they do with them.
