No Response at helpdesk- Terrible customer service

I ordered clothing items in November last year. One of the items that were delivered to me in December last year was not the same as depicted online. I took photos and send through an email on the 8th of December 2020 requesting that the incorrect item be collected from me and replaced with the correct item. I didn't receive any feedback for a month, despite a response from the auto-reply mailbox stating that my issue will be addressed within 48 hours. I followed up with a few more emails, and a phone call at the beginning of January. I was assured by the consultant that the issue would be resolved, and he would send an email confirming the collection and delivery details. Nothing came through. I followed up with a couple more emails and calls throughout January- each time the consultant indicates that the system is offline and they cannot assist. I request call-backs, which never transpire. I requested an escalation path- I get the response that the managers are not there. I ask for the manager contact details- they remain adamant that they're not allowed to give the details out. To date I have not received even one response to my various emails. I am really disgusted by the levels of service. I am a long standing customer and will definitely not purchase from MR Price in a hurry.
