Bad Service

I am really not happy with Regent Business School. I completed my Postgraduate Diploma in Supply Chain Management with them in 2025. My fees were paid in full. I told them I won't be able to attend the graduation ceremony so they must please send my certificate via the courier services. I was told I must wait after the May graduation and they will deliver the certificate. I send them an email again in June asking for them to deliver the certificate now I am told I must wait for the September/October graduation ceremony. I told them this is unfair because initially I was told to wait untill the May graduation ceremony is finish and they ignored me.
