Sealed battery unit leaked and no replacement

On 14 April 2015 we purchased an Inverter from the company which came with 2 \free"batteries. However we purchased an additional bigger battery to use as well. Invoice number 1500112. When the goods were delivered the bigger battery which is a sealed unit had fluid leaking out of it. The battery also had some other persons name written on the box. We lodged a complaint and they stated that it is not their fault but the couriers fault. We dealt with BuyFast and not a courier company when ordering online. <br> They initially made contact with us and assured us it would be resolved promptly. To date we have not had any further correspondence from BuyFast. This is a warning to all others not to purchase from this Company """
