Burnt Battery

I have purchased a Willards Battery from National Motor Spares (Phoenix) on Wednesday 27/12/2017. On the 30/12/2017 the battery melted and burnt to the core. When I contacted National and spoke to Vishen he advised that willards is closed and will only open on Wednesday 03/01/2018 and to bring in the battery. The battery was dropped off as advised and I was told that I will be contacted by Thursday. I have called National on Thursday as they have failed to Contact me and was told that Vishen is busy in a meeting and will call me.

No calls received. When I called again Vishen advised that he will call me back with feedback. Still no calls received.

It's now Friday 06/01/2018 and still no feedback. When I asked Vishen for a reference number that Willard has provided him, we find out that he has not contacted willards and the battery is sitting there with no attention.
