Very poor service from this company

One star is too many. My experience with this company is Very, very poor. Purchased 2 Deltec 105ah Batteries in 2017. Just after Warranty (Swell and not usable, Purchased two new ones in 2019. Just after warranty swells. Purchased 2 new ones in July 2021 with 24 Month Warranty. One of these started swelling three weeks ago. Took it in and sent away. Should return next week. After two weeks still not returned. Went today 25 June 2022 after 3rd week and was told only 1 year warranty. Although two of these batteries was on one 24volt Inverter which was purchased in Jan 2021 (Also new.). Very bad client service experienced and would not suggest any one to purchase these. I have learnt my lesson and will never ever purchase this brand again. Thanking you for nothing
