No service - No reply

Hello GoGas - is anybody there......... On Sunday 22nd June I tried to order a refill but my credit card was rejected. On Monday I called my bank, they checked and nothing was wrong with my card. I called your business and was cut off, left messages and eventually when I got through I was told someone would return my call. I also called Payfast and they said they could not do anything - the call would need to come from GO Gas....... Same on Tuesday, called, requested a call, wrote e-mails and when i eventually got through I was told someone would call me.............. I still not had a call or response so I have made alternative arrangements. I will no longer be doing business with you and am requesting collection of your cylinder and refund of my deposit. Due to other ratings I would like cash in exchange for the cylinder. If I do not get a response I will be taking this further.
