Payment

Final payment was made to cartrack for cancellation of contract, I sent proof but it amazes me that they call every single day harrasing me for payment my ref is : Tsha03235, on the proof it said 03235 they cannot fix the error even when there is proof of payment, *********** staff, I've emailed Sheldon Melly, Masego Retlabane, Jacquiline Mathabela all work for carrack they confirmed they got the proof I emailed what more do they want from me, I don't want to hear anything from this company
