Always great service and advise with my salt pool

I will never do business with Chris Sparkle Brite company again and will never recommend to anyone I know. They supposed to drained my pool, clean it, put fresh water back in and handle the service once a week afterward. Because my family and I just move down here and we never had pool before, we trusted them to do the job correctly. Well, they screwed up big time. They acid wash my pool after they drained out the water but they didnt do it right so now I have stains all over my pool. The stains just minor compare to the damage they done to the surface of the pool. The acid causes the sand in the surface to fall out so now my pump is clog and its going take lots of money to re-surface the pool again. What a terrible company.
