Penta Suzuki Montana bad service

My wife's Suzuki S Presso has gone into Penta Suzuki for the 3rd time in a couple of months to "reglue" the strips on the inside of the door panels that came loose. A very simple job, you might think, for a company and garage like Suzuki. 1st time I was told that the technician did not understand where the problem was when he read the job card, nobody thought of perhaps informing him, or to phone me. 2nd time I took it back. I was told that they did not have the glue to stick it back. 3rd time they stuck it with double-sided tape, which looked pathetic and did not hold for very long. 4th time, I think it was once again stuck with double-sided tape as I could only remove the sellotape this morning, will check later today, but what I could see is that it was stuck on skew.
