Frustrated client

I have been chatting to different agent on my aunt requesting that my account(premier to be downgrade to aspire) as it was upgraded by mistake almost a month later nothing has been done, i was told someone tried to call me, no call ever since i logged this incident even a missed call. it is honestly not fair to my as your client to receive such service and very frustrating, cause if i go on the app i will be told the same thing over and over yet no changes
