Poor Service ABsa

I have been receiving "Lapsed Policy" notices (4off) since 26.04.22 and have contacted ABSA House Insurance via email, telephonically and at local branch. I have provided proof of payment via EFT Standard Bank on 10.02.22, I have been assured that the payment has been received but not acredited to my account? . I have been assured telephonically that the poli8cy has been reinstated, and assured that an email conformation will be provided. This has still not taken place and having received 3 complaint ref C-***.04. C-***.04 . C-***2 30.04 all of which assured me that a consultant would contact me this also has not happened. I have repeatedly demanded written proof via email that the policy is in fact valid but to no avail. I have no option other than to seek legal advice as ABSA will not provide documented assurance that the policy has been reinstated despite having recieved the payment and verbally acknowleged this. Please advise, I am concerned that should I need to make a claim agaist the policy I will be told that it has lapsed.
