Cell C Refund due to Customer since 2 April 2020

On 2 April 2020 I made a payment of R840.00 to Cell C for a contract that was in areas. This payment would have brought the contract up to date. 4 weeks later the number had not been activated at which point I made my first call. I was informed that the contract had been deactivated and could not be reactivated. The commitment was made that someone would call me within 7 days to arrange the refund. By 11 June 2020 I had not received a call and phoned for the 2nd time. I was informed the Legal Department were not working due to Lockdown and I could not receive a refund until they began work again. On 7 August 2020 I was again informed I could only deal with Legal and someone would call be back. On 17 August my fourth phone call, I was informed I need to email the legal department, however, the email address can only be SMSed to me and not given over the phone. 40 minutes later and I have not received either of the two SMS's with the email address. Is this an indication of how Cell C treats their customers and *********ly keeps money not due to them?
