Rebel flavour

I have been a loyal Twisp customer now for about 4 years and religiously only buy the Rebel flavour. I have noticed that the flavour and product has constantly change over this time resulting in a unfavourable taste and non lasting coils when using the darker liquids. The taste is not as strong and full of flavour as it used to be but very light with a bland taste to it. I am now since yesterday on my 7th coil in just two weeks. I have complained about this had head office and have gotten a feedback that the product is still exactly the same, but it is definitely not. I can assure you that it is not the same Rebel that I had become to like when starting with twisping. I would also like to mention that I was at the Canal Walk store yesterday around 18:00 to complain again about the flavour and tested the Rebel in the Cue and same result, no full Rebel flavour. The employee working at that time also tested it himself and he agreed. So my question to Twisp is, are you concentrating to much on the new flavours? Is there still quality and tasting tests done to the Rebel liquid? I find it hard to believe as it definitely is not the same full Rebel flavour as what it used to be.
