TORONTO - Rogers Communications Inc. (TSX:RCI.B) is reimbursing hundreds of thousands of current and former customers a total of $30 million because of a billing mistake, the company said Friday.

Rogers said the money will go to about 300,000 subscribers to its Better Choice Bundles discount program who were overcharged.

Meanwhile, the company is waiving any payback fees for 200,000 customers who were underbilled under the program.

Affected customers are to be notified by letter starting June 22 and the correct discount will be applied within their next two bills, Rogers said.

The inaccuracy is a result of administrative error and system related issues, the company said, adding that it varies for each customer depending on the number of services they have and how long they've been in the program.

"Once we identified the issue, we initiated a comprehensive review of current and former customer accounts to identify those that were not correctly billed," Phil Hartling, senior vice-president, consumer segment, said in a news release.

"We have been working around the clock to make this right and we apologize to our affected customers."

Existing under-discounted customers will receive a credit on their account while former customers will receive a cheque. Any unclaimed funds by former customers will be donated to charity.

Rogers introduced the Better Choice Bundles program to offer customers a discount when they purchase two or more eligible communications services with a two-year contract term and a consolidated monthly invoice.
