Cartrack Incompantance

My payment was a bit late this month as I was waiting for funds to become cleared. I have made a payment from their online payment portal on 2024-09-13 and I have s screenshot from the completed payment indicating that the payment has been done. Then after that I got harrased continualy and received non stop phone calls and messages stating that I did not make a payment. On 23-09-20254, I paid a second payment via their online portal and have screenshots of the entire process as well as the message stating that the funds have been deducted from my bank account. I then sent a whatsapp message to their whatsapp line and told them that they can now see that I paid teice. They then rep**** yes. I also got a message stating initially that the payment will be cleared in 72 hourse. After being continually harassed and sending all the proof of payment information to them more than 20 times, I gor a message stating thanks for the payment and that the payment will thake 48 hours to reflect, Yesterday they still kept on harassing me and calling me non stop ( I had to block all their numbers). This morning I got some funds paid into my account and they decucted the money from the account despite me making 2 payments and sending them 20 messages with the proof of payment, Now I sent them a message again asking what is going on and I did not receive an appology even from them just a message that a refund will be requested. They NEVER ONCE appologised for their mistakes and for the harassment. I have now asked for them to cancel my contract and STILL they come up with problems and NO results. This is unacceptable.
