Commerce Commission complaints over Spark's streaming debacle are continuing to rise in recent days.
Streaming of the All Blacks first World Cup match against the Springboks was plagued with periods of reduced video quality such as pixelation and buffering.
And the Wales v Australia match last Sunday was again disrupted with technical difficulties, with complaints about vision lagging and audio issues.

On Monday the Commerce Commission said it had received 13 complaints since the All Blacks V Springboks game, Stuff reports. And since that, it has received another six complaints.
A Commerce Commission spokesperson confirmed that the complaints were being assessed, but no investigation had begun.
Spark Sport uploaded a refund request form on Sunday, detailing three different refund options for those who purchased a Match Pass or Tournament Pass for the New Zealand versus South Africa game.
"Customers who feel unhappy with their viewing experience of the All Blacks v South Africa pool match pass can receive a refund," Spark said.
"Customers who purchased an All Blacks vs South Africa Match Pass can receive a full refund; those who purchased a Tournament Pass and wish to leave the service can also receive a full refund; and those who wish to carry on with the service, can receive a partial 15 percent refund of their Tournament Pass price.
"Unhappy customers who have activated a Spark Sport subscription via a voucher code can also receive a full or partial refund."
All requests had to be submitted before September 29. Spark Sport hasn't said how many refunds have been issued.
