Very poor service

I have been on contact with Virgin active as of October 2018. When I signed on, the agent assisting me erroneously informed me that the discount for being on Momentum Multiply is only claimed at the end of the membership contract. I comp**** and signed up on a 1 year contract inclusive of Club V. A year later in October 2019 I found that the agent who signed me on was supposed to have app**** the discount at the beginning of the contract, which led to a loss of approximately 800 for me. The agent assisting me with my new contract advised that they will refund me 2 months worth of gym membership to make up for the mistake with the discount. As of October 2019, my account has been debited monthly with no refund or credit for 2 months as promised, after months of following up. I am fed up to say the least. My account was debited today again without any communication or rectification of the issue. The customer service from the accounts department is poor, considering the time and effort I have made towards getting this issue finalized. I feel helpless and ******!
