Disappointed and disgusted

I app**** sent my cv aswell as my qualifications to this foundation. I received a call from them in January to say they’ll add me in a group on WhatsApp the following week. I then waited and haven’t received any group add. I then decided to email them and ask what’s happening with the WhatsApp group as I wasn’t added yet. The lady responded with she added me and sent the number she used to add me on I then told her that an incorrect number and then added the correct one into the email.I then never received a response back thinking they’ll correct it and add me with no luck at all. I then emailed again few days after with no response whatsoever from them. I feel this is very unfair as I had my hopes up high! I’m very disappointed and wouldn’t recommend this to anybody in the future.
