Netstar shocking management and customer service!!!

I’ve been a customer of Netstar for 6 years. About 6 months ago I received a update offer at a lower price on 2 vehicles which I agreed to. What then happened was a circus. 1. Firstly 2 different installers arrived with 2 different installation instructions. 2. After getting that done they both went away “for correct instructions “” 3. It took 3 weeks and who knows how many phone calls I received 2 more phone calls to arrange installation. 4. Sure enough 10 days later 2 installers appeared and asked me which unit I wanted installed. 5. My daughter in law meanwhile had 3 visits from indifferent installers over a month before the right installation was done on her car 6. Now the fun really starts. I have always been charged a combine subscription for my two cars. statements are raised for 2 cars. 7. After 2 months I receive about 6 different calls from the “legal “ division” I respect of my “new” account which is unpaid - wrong bank, wrong account numbers. 8 a quick check confirms charges of 4 charges for 2 cars. 9. 4 months later and after heaven knows how many different conversations with *****s I finally get the accounts sorted out with a refund! 10. Tonight I needed an AA call out to replace a battery. I then receive an emergency message to call back to reset my tracker unit. 11. Netstar leaves me a number to call. The voice message tells me I’m through to the admin office and I must call back in office hours!!!!! 12. Guess whose cancelling Netstar tomorrow morning???!!!!!
