My call minutes are incorrectly logged on your bill, subsequently I purchased additional minutes for a month when this was unnecessary.
On 02/06/2020 I have been billed £5.99 for a call of 4 hours, 26 minutes and 52 seconds at 13:01:03 to an 0333 number. According to your own billing logs, the next call to a different number is at 13:06:45 (lasting 30 minutes). Firstly 03 numbers are included in my call package whilst I have minutes available, secondly your own logs show it is not possible for my call to have lasted over 4 hours.
For the 03 call on 02/06/2020 at 13:01 my call logs show 46 seconds.
After being warned in the app my 300 minutes was almost used, I purchased an additional 500 minutes on 03/06/2020 for £5.00
Your incorrect logging of the call on the 2nd means my purchase on the 3rd was not required. Your billing error means I have been incorrectly charged an additional £11.99 on my statement and I request a refund.
