No Rewards from W-Rewards

I am very disappointed in Woolworth's customer service over this lockdown period. Firstly, when I tried to purchase a voucher online, every denomination was 'sold out'. Surely vouchers can be issued digitally, especially in these times. Secondly, I have complained twice that certain promotions (particularly the Pick and Mix fruit) are not being app**** when shopping online. I have bought 3 of the pick and mix containers for weeks without being given the discount. Lastly, I emailed Woolworths to express my frustration at being unable to use W-Rewards vouchers when shopping online and received a completely generic reply detailing the various debit and credit cards I can use for payment. This did not address my query at all. I feel that by shopping online during this time, I am being responsible, yet I am being penalised by not being able to use the Rewards vouchers I receive online / download via the app.
