Scamming

I purchased both of the SEE LSB. I received them and apart from that I noticed I received some crystals although I had received all characters. Being a bit confused I just collected everything from my inbox and moved on. The following day I checked my bank acc and noticed I was charged a total of 4 times for the LSBs. In game support said I can’t get a refund because I collected the crystals??? So CG screws up and somehow charges me 2 extra times (apart from the 2 original lsb) for packs you can only buy ONCE each and then they charge extra and send crystals for UNAUTHORIZED purchases????
