Pay for programming remotes

Today I went to Builders for them to assist me yo re-programme x3 remotes. I have done this many manyc times before and never paid. All of a sudden there is a R20 fee per remote to be paid and I was not told this before doing it if I knew that I would have taken it to someone else to do it as it is open circuit remotes. Not happy with their attitudes and all of a sudden it "it is not free" they lost a very good customer today. I will avoid them as far as possible
