Poor service

Good day just want to say how disappointed I am in the service recieved from Nets star. On the 13th December 2022 I renewed my contract with them I gave them adress and contact details of where my vehicle will be for fitment of the new tracking unit, on the 28th I still have had no contact about fitment I then phoned and was told I will be phoned back in 2 hours to confirm fitment it is now the 29th and still no phone call. I then phoned them again to find out what is going on only to be told they will come and do fitment tomorrow morning. But why did I have to call them, very poor service Netstar shame on you.
