How many times should one try and resolve and issue?

I have been receiving emails meant for a mrs. Gona Reddy for some time now. While it may seem harmless, it totally annoys me, as it is spam email which I can't unsubscribe to (I have tried to unsubscribe, but I still receive it). In addition, I do want to receive my own emails. Linked to this issue is that my tier status is not even close to reflecting my own purchases - perhaps it is reflecting the purchase of Mrs. Reddy?

I have take up this matter with their call centre at least 3 times, and via email at least 3 or 4 times over several months, plus of course the unsuccessful "unsubscribe".

My last attempt to resolve this matter was an email on 9 February, where I even told them how many times I have tries to have this matter resolved, and that if this last resort does not help, I will go to Hello Peter, as I am doing now. A lady called Marleine Dollman did respond within a few hours. However, she did not address the matter of the unwanted emails - simply asked me for an example of the unwanted emails, which I immediately rep**** to her, but no response yet. Should she not be able to look this up on their system? Especially since I provided a name? Also, she gave me a detailed explanation of how tier status work, without addressing my concern and/or checking that my purchases are actually reflected.

I know this is a small irritation, but based on the number of times I have tried to resolve it, as well as numerous false promises that this matter is indeed resolved, coupled with the image Woolworhts projects of good customer service, this is becoming a major irritation to me.

PLEASE, SOMEONE COMPETENT, ASSIST ME AND REMOVE THIS SPAM FROM MY INBOX! Also, if my own purchases could reflect on my tier status, as I am sure is the intention, that would be great!!
