Grossly overcharged, do not expect them to do anything if something goes wrong

Used Lemoncool for close to 2 years now. I just moved house to a new location and as usual, called them up to service my aircon in new place. The brand and aircon units in both homes are exactly the same. However, i was grossly overcharged in thr new place maybe because I was parked as a NEW customer. I called back Lemoncool and asked for a reasonable explaination of why i am bring charged such exobitant prices which were so different from my last bill (just 2 mths before in the previous address). I was given a holding statement, saying they would investigate and come back to me. I have not heard from them and all my calls to Lemoncool have been ignored / blocked since. This is a blatant rip off case. Instead of having good customer recovery, they rather block the customer who's been victimized. With this recent experience, i would NOT recommand them to anyone. You will never know when you are going to be ripped off despite being a returning customer for years. Considering lodging this with CASE. This is the type of business behaviour that gives the industry a bad name.
