Sick and tired of Old Mutual

If I could I would give old mutual a zero. I am very frustrated and it is with sadness that it has to resort to this. I have been receiving low level service from old mutual and its come to a point where I am just tired. I cancelled 2 of my max investment policies in May that's where the issue started. I had to call in multiple times and I was told to fill in forms and than at some point I was told to write a letter cancelling and this was me communicating with them all the time. That was done eventually and I received a paid up letter and I thought that would be the end of everything but no. They continued to debit from my persal from May till now November and I fail to understand why I'm still paying. Again no communication , I had to use my airtime and and call them sometimes to no avail and at times I would get transferred until I run out of airtime. I sent multiple emails no response, the last response was recently where they were requesting documents I had already sent on my initial email. Today I was told after a long wait that the refund is being processed but first I was told R600 I'd being refunded for October, How as they have been debiting +/-R800. I called again because I am so confused, how am I getting R600 when R800 has been debited from my persal for almost 6 months. To make matters worse the refund process will take a whole month, how is that possible, because If I miss a payment you call non stop and expect immediate payment but I have to wait months for my matters to be resolved. This is utter *******. I'm so disappointed.
