GREAT LENGTHS EXTENSIONS

I have been wearing great lengths for nearly 10 years I wear it as it is a lifestyle fir me due to extremely fine hair after so many years you know the aftercare and product use I have been given a set of 140 strands that is so bad that it knots as if you wearing fiver Hair it actually feels like co**** horse hair I have had it in for 7 weeks lost more than 20 strands so far launched complaints and what to they do... everything but replace they have the one excuse after the other cutting my hair for the 3rd time now I have done numerous treatments and nothing works. Where I normally replace my set every six months I will have to before 3 months if I'm lucky I am so disappointed in the product and service received that that they are not prepared to replace my hair knowing the state it's in and the consultant from great lengths telling me \I have news for you but your set is not going to last 3 months"so they are prepared to give you a free sample of mask knowing the product is off and saying to me if I get a new set dine in future to check the hair before installation as if I'm a hairdresser!!! Very angry?. I can't believe this is how u treat such old customers"""
