I'm Covid-19 Positive, MoiMooi refuses to cancel membership

I'd like to complain about MoiMooi's Spa Head Office. I had a call from the sales lady in August, referred by a friend. When this lady made me an offer I was Covid-19 Positive, I was actually in quarantine. I remember making it clear to her that I'm taking medication, I'm Covid-19 Positive so I cannot join any Spa let alone be massaged by anyone because I'm positive. I also remember telling her that I'm on medication, but she kept convincing me to sign up now, because I don't have to come to the Spa I can come when I get better, she also convinced me that the special expires end of August so if I take the offer now, I can start coming beginning of October. Not once or twice I told her that I'm not sure because of the virus. She convinced me, I then said it's okay. Unfortunately I became ill again in September (the same symptoms are back), I then decided to write an email 20 days prior and cancel before they could deduct the joining fee and monthly installment. Today I received a very disturbing call from the Head Office threatening me that I am a legal member from the day I gave the "sales lady" my banking details. It does not matter that I kept telling her I'm sick, I'm under medication, I'm Covid-19 positive. No! clearly they don't care about my well being, all they care about is that I gave them my banking details (money) and their increase in membership, that is sick! They don't even care about their staff, after numerous times I said I'm positive, you are still eager to offer me the contract? All they care about is money, Money, money, money! They're threatening me with additional legal costs and cancellation fee. With this kind of attitude, I don't think it is wise to recommend this Spa to anyone. If anyone wants to join this Spa, please read me before you join.
