Pathetic service

I've been a Miladys client for more than 20 years ( ********** 179). After my husband was retrenched in Jan 2017 I tried to claim from my 360 Joint Plan, his former employer refused to fill in the claim form, due to the ridiculous questions on it. I then decided to cancel this 360 Joint Plan. I phoned the call centre, I went into the store - no joy. Then, since March 2018 I've been mailing them 2 weekly, trying to get this Plan stopped. It is July now, I just received my statement and the Joint Plan is still on there. When they phoned me about 2 months ago, I explained my problem, the lady said somebody will phone me back in 3- 5 working days, nothing yet. I am paying R55 a month for something that I cannot use and tried to stop for nearly 6 months now
