Poor Services

How difficult can it be to cancel a membership with Planet Fitness? Sent a cancellation request on 26/03/2020 due to PF agents not keeping to agreements (Arranged for a lower tariff as I wanted to cancel my membership previously and they convinced me I would pay the special rate in March, only to discover they placed me back on the normal R580pm tariff!) Until today there has been no responses, no confirmations, only SMS's as if I am still a member. I can understand that it is difficult working from home for some companies but still it is ethical to set up a form of communication for your customers to stay in contact! Poor service!
