Fourth day and still no tracker installation

I'm extremely disappointed in Netstar's service and will definitely not recommend anyone to use them.

Last week I purchased a car through Raymond Wolstenholme Motors, they emailed them on Wednesday to advise that we'd need a tracker installed because the car can't be released without one. They advised me that it would take up to 3 days and confirmed that it would be done before Tuesday. This was confirmed in a voice note.

Today's obviously Tuesday and soon the working day will be over and I'm still not getting any feedback despite the salesman informing me that they would be installing it today.

The service I've received from RWM has been impeccable but I can't say the same about Netstar - their service is an anti-climax. I feel like I've not been made a priority at all.

I've messaged them to complain on FB but they've simply not responded, I don't know what else to do. I've made plans based on the fact that I should be getting my car today for the latest but will most likely have to make alternative arrangements as it doesn't look like they'll be coming out today - which is a huge inconvenience to me.

I am quite frankly disgusted at their disregard and lack of respect for me as a customer.
