No accountability

I have been struggling to get my note 9 repaired/replaced since March 2019. If has been in for repair more than seven times and I never received it without a fault back from Samsung's approved repair centers,

After many complaints I was "helped" by Herman Mashaya and at the time I believed that it will get sorted, he promised me that he would get the device collected and taken to Samsung head office,

It was collected but now 12 days later I learn it never went to head office as promised but to a repair shop in a mall somewhere,

The phone have software problems due to wrong software being loaded by Samsung in a previous repair, it it went back about four times to get it sorted,

Now the repair shop state that phone is fixed and a replacement is not needed, but it is not. It is not as it was before and also I have a second note 9 to compare it to

I really need someone to assist in getting this sorted
