**************** on gas cylinder

I bought a 48kg gas cylinder from Builders Kempton Park on the 29 June 2020. Today 7 weeks later the gas is finished and we only use this for cooking. I have been using this size for 3 years now and it last us 9 months on average. I honestly think we have been given an almost empty filter here because also at the time of me buying it there was a shortage of gas. I cannot accept this ****************
