ABSA ignores 5 email instructions to close my account and now claiming I owe them money.

On 28/08 your ATM told me Chip Damaged. I was forced to use FNB. I asked ABSA to reverse the ATM FEE for ABSA. On 14/9 i followed up via email again. No reply. On 2nd Oct, i emailed an instruction to close my account. No response. On 12 Oct, i sent another email on closing my account. No response. On 29 Oct, 3rd email on closing the account. No response. On 4th November, ABSA continues to ignore my emails. On 23rd November, guess what??? Still no response. AND as I expected, the account would fall into a minus because ABSA looking for their account fees and GUESS WHAT...Now ABSA suddenly floods me with SMS's threatening me to rectify my overdraft. Firstly, I do not have an O/D nor have I ever app**** for one. I have all the emails sent to ABSA as proof for when this matter will go to the Ombudsman. My account was in a positive balance when I notified you 2 months ago to close my account.
