Not sure if anyone can advise. Tried to call Talk Talk and there's no one in Billing available due to the Covid issue. I have recently upgraded my contract with Talk Talk and Included International Max Call Boost which the Talk Talk sales person informed me gave me 1000 free minutes to International mobiles/ landlines in specific countries. My partner has called family for well under 1000 minutes in one of the included countries and we now have a bill for £54. This is the bill we will need to pay by mid April so technically it hasn't been issued to us yet but I'm wondering if the system generates a current cost on your account which is then subtracted back off when the bill is sent, thus meaning the calls are free as promised. Does anyone know if this is the case please?
