Review Worst experience I ever had...Sadiq Gas is the worst company

Sadiq Gas is the Worst gas company of bahrain. They are very rude to their customer. They charge me extra money twice for valve changing and didn't provide a receipt. Now when I asked them to deliver cylinder, they are asking money again for the same. So ultimately each time I asked for gas, they are charging me 4/5 bd extra.
And top of that super rude attitude.
Never experienced such a worst company in my life.
