Changing our gas supplier

[trees]

We have a 1000kg propane tank in our back garden, installed by Vitogaz.

At the time, we chose Vitogaz as they answered the phone when called and had a local office.

Since then, their local office has closed[:(]

We are now dissatisfied with them on the following reasons:

1. They seem to take quite a while to refill us when we ring.

2. Their bill thus almost always arrives when we are back in the UK.

3. The ONLY way we can pay them is by cheque, no credit, or debit, cards, no cash locally.[:(]

This often leads us into owing them money until we next visit France to put some in our French account.

I know we SHOULD keep enough in there, but often circumstances dictate otherwise.

So.........how easy would it be to change supplier, preferably to one with more up to date accounting?

Has anyone done it?

Thanks.
