Policy lapsed because ignorance and fault by old mutual

I have been with old mutual for years now. In April 2019 I resigned from the department of Health and started working for another department. I then informed old mutual about this and requested that they update this. I also submitted all the necessary documents in order for it to continue deducting from my persal to my advisor and in Pretoria old mutual offices. I was then informed by my advisor that they are currently having problems deducting from my persal. I then came to an agreement with my advisor from old mutual that if they are unsuccessful getting the premium from my persal it shud be deducted from my bank account every month end (30/31 st of the month). This went on until the 23rd of January 2020 where I saw a deduction from old mutual that did go through as there were no funds in my account. I then called the old mutual advisor to enquire about this,he was also not aware of this and suspected that it might have been an error done by someone and informed me that the deduction will continue deducting on month end. On the 3rd of February an amount of R234 and R1 232. The one for 234 went through went but the one for R1 232 did not as the amount was above my normal premium which is R733. I then called the advisor Again to enquire of what was happening and he suspected that they had doubled the premiums. I then asked what was going to happen to my policy as they did not get the full amount because of this error they did. He called me later and asked if perhaps I could pay double at the end of the month. I told him I did not have a problem with that, but wanted to know what was going to happen to the R234 they took this month, he said I might be refunded. We ended the conversation that at the end of the month they will deduct twice as they were still struggling to deduct from my persal. Today the 7th of February the advisor called to inform me that my policy has lapsed because I had missed 2 premiums. This rally shocked me as they had deducted on the 31st of December 2019 the full premium. I am left with no life, funeral and other covers. I feel like I have been ********** and soo dissaponted by Old mutual after soo many years being with this company.
