I am bitterly disappointed in Pandora SA service

I bought some items during the 3 for 2 sale and following sale in June/July. If you buy an item for R379 or more you get a loyalty point per item. I am still waiting for my points- I have emailed 3 x enquiring re my missing points. I understand that it may take some time after the sale but this is 2 months later and not even 1 reply to my enquires. The shops themselves are unable to help if products are bought online.
