Lousy services

On 28 February 2022 I went to Clicks @ Pick n pay Hyper in Brackenfell to get my second JAB. I need the vaccination certificate for work. However up to today they have not updated my details I called the vaccination hot line and I was informed that details for my second JAB don't appear on the system. I called the many 'n times with no luck they just don't answer the phone. I am unable to go back there because I am busy with work.
