Poor customer service to say the least

I have raised a billing query with Netstar on the 5th of May 2019 where I was advised that they have added another vehicle to my account and have billed me for that, upon our discussion with the consultant they were going to credit my account and not debit me for April and May and only debit a portion for my June premium. However this has not happened I sent them a number of email which most of them are not responded to I am tired of calling their call Centre cause what they say over the phone is not what they say on e-mail. My last email to them a request of the recording where I have agreed to pay an amount R655 for installation of the device to date I have not received a response to them.

I must say the service is appalling to say the least how can it take you guys 4 months to resolve a billing query??? I have lost all confidence in your service and doubt that you guys will be able to recover my vehicle should the unfortunate happen, the reason why I took your device is because it was a compulsory requirement by my insurance.
