It seems that, for example, if you have a contract with 'True Vision' you have to agree to pay petrol money before they'll come out to sort out a problem regarding their equipment. When I first obtained 'True Vision' they'd come out without charging. I've tried to explain to me wife that it's their responsibility repair faulty equipment. You don't pay petrol money to TOT or the Electricity Board when we call them out. But she won't have it that we shouldn't pay. Talk about banging me head against the wall.
Had a problem once where we had a new aircon fitted. It worked okay before the engineers left but the first night it didn't. Called up the installers and they sent out the 2 men who fitted the thing. They found the gas had escaped through a leaking pipe. They repaired that but would not refill the aircon again unless I paid 500 Baht. No 500 Baht, no gas. Fcuking wankers.
