Overcharged, no feedback

I am totally appalled at the non-existent service and lies I have received from Netstar. This is my experience with this company over the past few months:

1. I previously had a Sleuth device fitted in my vehicle. Once my initial 36 month contract had come to an end, the agent who I dealt with sold me a "Safe & Sound" device, as she said that was the new entry level device, and I wasn't given the option to replace the Sleuth with a similarly priced device. It was only after speaking to another of the Netstar agents that I was told about the "Safe & Sound Nano" - this was never offered to me. Clearly I was being **** to.

2. On 1 September my bank account was debited with R362.99 (instead of R139). I called Netstar to query this on 5 September, and I was told it would be corrected. Nothing happened.

On 1 October, I was incorrectly debited again ( R169 instead of R139). Called again on 12 October, and Netstar acknowledged the error of the past 2 months, and referred the query to the accounts department. I was given a reference number of CAS ********** and was promised a call back by the end of the day. Did not receive any feedback

I emailed Netstar on 16 October to follow up using the reference number. Jeverne Naidoo responded to say my query had been sent to the relevant department for assistance. Received no further feedback.

On 1 November I was incorrectly debited YET AGAIN, and still no refund from the previous incorrectly debited months. I emailed Jeverne Naidoo again on 13 November to follow up and I was told that Netstar would refund the pro rata amount within 7 to 10 working days. I responded and said it was unacceptable and would prefer to cancel my contract and asked for details on how to cancel. My request was ignored.

I have just checked my bank account, and once again, on 1 December I was incorrectly debited. Also, to date I have still not received the promised refund.

I am so sick and tired of continually trying to resolve this with people who are incapable of providing a basic service. If Netstar can't sort out a basic billing issue, how can I rely on them to recover my vehicle should it be ******?

Should anyone from Netstar want to contact me, I am available by phone after 6pm. Alternatively, please email me during working hours.
