Eye opener on renting

Worst experience in the last 4 year I have been renting form Woodfords. I wish to warn all that please check the following before leaving the on picking up the vehicle from any car rental company. I have been charged for 2 tyre's that had bubbles on the tyre's. This is not something that we are made aware of when picking up the vehicle and I suggest that you ask the agent to check that and declare that all are intact. When I picked up the vehicle from Sandton the Agent which I know from dealing with him before that the vehicle are all fie and no inspection is needed. Mistake number 1. On returning the vehicle I was informed that 1 tyre had a bubble but a 2 weeks later I was invoiced for 2 tyres that had bubbles without any communication or discussion
