Pensioners funeral covers that are being fiddled with intentionally

I had funeral cover for my grandmother with old mutual dor mire thatn 10 years. Reswnlty they started to debit veey late., that nadw ne muss few payments. They sent me an sms to pay missed payments so that they can reinstate the policy. I did that ib December. Called them to update the policy. Theu started to give me excuses. The still debited in Dec. Come January they sebt me another sms now according to their records i still short dor them to reinstate the policy. Paid and sent a proof of payment. Then no feedback. I called again they told me they will escalate as the payment reflects but nothing is been updated yet. And no one can be able to do that as the department they are escalating to they don't take calls. I was promised to be given feedback since last week Wednesday still nothing teied to call yesterday. I was on hold for more than 40 min. Eventually i hace given up. Still nothing from them. Let me remind you fhat the person insured is 86 years of age.
