Shocking Service

My Russel Hobbs Gas Heater stopped working so I took it into their Depot in Maitland and they sent it to be Johannesburg to be fixed. Despite me making at least two calls trying to expedite it's return, it took at least 4 weeks to come back to Cape Town with a note saying that there was nothing wrong with it and my issue was probably due to operator's error. One of the employees loaded it into my car for me and a couple of days later, I attempted to connect it to a cylinder and get it working. Sadly I could not do this as the unit which emits the flame was lying loose in the unit, so it was totally dysfunctional. I phoned Maitland and was told to bring it in. I said that since it appeared to me that the heater was broken by them, they should collect it from me to save me having to drive back to Maitland. I was told to e mail them and it would be arranged. I sent this e mail on the 2nd July and noticed that it was read, but as at today (10th July) I have have not had the courtesy of a response.. So I am still sitting without heat in this freezing Cape Town Weather.
