car great , picking up OK , return rip off.

The car itself was fine but on returning I had the car inspected. It was visually inspected and stated the condition was fine , the condition on fuel full to full it was confirmed this was fine on return. I requested as final invoice but the company stated it could not do this as there were road tolls to consider. It was stated that I would be email a invoice with in seven days. As I thought this never arrived and my bank statement shows I was invoice for £50 pound followed by £19 pounds. The £19 pounds I suspect was for road tolls the £ 50 pound was I suspect a spurious charge that the company are trying there luck on. This company if you look at there reviews have a very poor history of doing this but overall life is too short and its only £ 50 pounds . I will just have to be more careful in the future and not hire from the company again, As a overall review of how car hire operates car hire companies operate they request we sign for the condition of the vehicle , the vehicle is full of fuel and for any damages. Would it not be fair for the car hire company to also sign for this on return. I did ask for this but it was refused when I returned the car. Overall poor performance as £ 50 pound was taken from my account with no justification , no final invoice supplied and I personally think the company is just taking me for a ride but to be honest I can't do with the hassle of fighting it so I will live with it but will never use the company again - bit short sighted if you ask me. Any comment would be gratefully received and if you would like to justify the £ 50 was take as well as the £ 19 taken it would be an insight and we could take it from there
