Absa life

Good day Please note that I have a policy with absa life and was informed that the policy was going to lapze in November so I went into the bank and advised them that I need to reinstate the policy. When at the bank I then encountered problems at the atm and the teller in the bank as it kept coming up as an error and they called the call center and informed me that they will get back to me regarding the query. On the 25th of November they called and I did an immediate payment and was informed that the policy will be reinstated and my next premium will be on the 15th of December and to my knowledge it will be the normal premium that I pay every month as I received an sms. I then go and put that amount into my account and a day later I see the it has been reversed as the policy is in arrears yet to my knowledge if I paid in November why would it be in arrears and if it was not the right amount that I paid why was I not informed about this. Today I received an email advising that the policy is now lapzed again. I have emailed them and they advised that I have missed a payment. Why was this not communicated to me in November when the consultant called and why was I given the wrong amount to pay?
