Complaint of bad service

I purchase a Hp Scanjet Pro F1 Flatbed Scanner from Makro online I did receive my unit unpacked it, connected it and found that it has a fault, I did an online return or replacement and no1 had contacted me I called many times wasting my time and money speaking to different staff they take down all my info and cut my call. I received an email from Patricia and she told he to contact Hp direct its an overseas no. and they told me to contact Makro for a refund to date my problem is not sorted out I only used the item once it was bought for business use now I am stranded very poor service from Makro online. I called again today 09.07.2020 and the guy tells me that its not their product they sell for market place but on the online page Makro does not say this (false advertising), I paid Makro I need Makro to sort out the problem I spent so much time and calls to no avail.
