Review Complaint

I was a passenger today at almost 5p.m in lopha KCT 267T en route ruiru. While boarding the matatu, the price on the board and that was been announced was kahawa, ku 60.. Ruiru ndani 70. When we departed and the tout asked for the fare I gave him my 100 Bob and as he was collecting from other passengers,he suddenly changed the fare to 80 Bob to ruiru n the women started consulting if the fare wasn't 70 Bob as it was when we boarded. Long story short we refused to be charged extra n he asked if we wanted to shout for all the other passengers to hear. He accepted one lady's 70 Bob n continued. After collecting from the rest he came to me asking how much I wanted to pay as everyone else has accepted to pay 80bob. I asked for my change of 30 Bob which he said he didn't have n asked where I was alighting. When I was alighting, I have asked for my change only for him to give me a warning of a next time. Before he finished I have told him just give me my change or I will take the vehicles plate and report. He has thrown my change on the ground and told me I can take the plates. What he has done was rude and he should be fired or suspended if this is a first complain considering he overpriced all the other passengers on who knows if he was planning to pocket the extra money. Paying 80 Bob is not the issue but let the price on the ground be what is asked when one is in the bus.
