Poor service(very)

Ive been with cartrack since may 2019 with no issues, premiuma paid monthly no arrears. On 15.12.2022 i accidentally made an error payment to them. Called cartrack immediately and they advised that they can do a refund once payment reflects. 19.12.2022 i emailed them my bank confirmation letter and a POP (as they advised payment still didn't reflect). Today being 05.01.2023 NO REFUND OR COMMUNICATION from them. I have called numerous times and the consultants i speak to will send Ayanda and Lerato emails to call me back as they cannot transfer my calls directly to them. NO calls, no refund If this is the level of care I receive for R1640 I pray to God that they dont ***** my car. Absolutely pathetic, this was an error payment and i am expecting my refund by 06.01.2023 or i would need to seek legal advise!!
