SaskTel is Canada’s fourth largest carrier and has been preparing its network for LTE deployment in early February 2013. Along with the hardware installations, upgraded system installations are apparently the culprit behind the error.
The good news is that SaskTel is proactively working on issuing automatic credits to customer accounts with incorrect data billing. If you are in the great white north, and your billing cycle fell between November 23rd and the 29th, and you are affected by the problem, SaskTel will call you and send you a letter outlining how the error is being corrected. December bills will be automatically adjusted, payments to the November bill will not be required. Late fees and interest will be waived and the correct amount for November will carry forward to December.
If you are set up on an automatic payment arrangement, no payment will be processed, the correct November balance will carry forward and normal billing will resume in December with no extra fees.
