My Gas - Terrible Service

The service has never been great from this company and has steadily gone from worse to bad to absolutely awful!. For one, during the winter months, you have to wait 48 hours to have a gas cylindar replaced, that is far too long and wish they could up their game here given that other companies can assist faster. Then, once I returned the gas cylindar in September, two months later I still do not have my refund. How is it possible for a company and its employees, not to have in place an efficient refund process. I've been given excuse after excuse such as "need two signatures for a refund" - yeah right, seems to me that the company is holding onto MY MONEY!!!! Give it back!
