AFrox great deal - read the fine print

We started buying gas from Afrox end of 2016. Initially we had great service, until our rep left Afrox. Every December the Stikland branch closes and then we have to get deliveries form Epping. In the past three years nobody answered the phones in the Epping depot during December and January. We tried calling the only other listed number and get to the big corporate favourite... (Yes, you guessed it) a call center. They are very friendly and utterly useless as they too could not get through to the Epping branch during the past three year's holiday period. We regularly get an email that ask us to rate their service. An utter waste of time. Nothing gets done. To rub salt in the wounds, we just got hit by a massive increase. Over a 37,5 month period, the average price increase was 34,7% per year. On complaining to Nathanael (Internal Sales and Territory Manager), he sends us the fine print in their terms that allows them to do with the price what they like (without notice of any kind). This is the same person that assured us in December that he is not going away and will always be available on his cell (since the depot does not pick up their phones), and then he too disappeared. Guess what? This customer is gone. PS We are pretty sure we did not sign these terms, but will go digging in the archives before paying.
