DEPOSIT REFUND

I served notice as i was moving out of the complex i sent a notice beginning of the month. Got a response from Antonio that he agree to my notice, i sent a follow up email as a reminder to pay my deposit, still no response, the landline rings non stop no response. i communicated with some one on their WhatsApp line, promised to get back to me still nothing. Spoke to some lady who said she's on maternity leave but she will assist i sent the notice the same time i sent notice to the complex. now they are no longer taking my calls, I WANT MY DEPOSIT BACK
