Exteme lack of service, not even bad - despicable!!!

I logged a complaint with Pick n Pay ASAP on the 3rd of March, at the time it was over 10 emails and 2 phone calls later with no assistance and eventually wrote a review on HelloPeter of which they advised was resolved, it was not. I had to then following up and now 18 emails and phone calls later, given 3 vouchers of which all did not work, I immediately advised and have a paper trail of this, I then ordered again and had 1 Rama brick short and tried to complain on the app and my complaint was rejected, I tried calling and opted to leave 2 messages as the calls were not being answered and to date have not been called back. This is discussing service and I am appalled at the complete lack of service! I would like a refund on my items.
