Disgraceful service all round. The box I had in my car was complete rubbish. I was told that it would decrease my score if I drove after 10pm however it decreased my score after 8pm. My acceleration constantly decreased also...upon ringing Hastings smartmiles I was told to ?pretend you have a bucket of water in the passenger seat and try not to spill it when you accelerate?. Although this is ridiculous advice I tried it...the score still continued to decrease. I also had several issues with payments. They told me no more payments were required and I was actually due a refund, to which they then took ?120 out of my account two days later. This put me into an overdraft that I don?t actually have so my credit score has now been affected. Terrible customer service on the phone during this time. I was literally told I was a liar on the phone. I was then told I wasn?t allowed to put a complaint in. Would never recommend these to anyone!
