The heat wave that ripped through Melbourne has contributed to the headache that Vodafone has been experiencing in Australia. The heat seemed to have caused the outage for many Vodafone customers Australia wide.

In a statement, the company attributed the problems to an air conditioning fault at their Tullamarine switch at around 7.45pm. This problem caused disruptions to 15 percent of their voice calls nation wide.

Technicians were on site immediately and more were sent to sort out the issue. The problem also affect other people trying to contact Vodafone mobile phones.

The problem persisted for a few hours and Vodafone stated that it got things up and running at about 11.45PM.

Vodafone has had a bad run of issues over the past few years which has seen them shed hundres of thousands of customers. To stem the flow, they have had to offer excellent deals on plans as well as enticing customers with a Vodafone promo code.
