Elektricity price

Hi, I have recently made a switch to your company on the 10th this month. When I was switching to bulb on your website the unit rate was showing All kWh 13.503p and that is the price we have agreed on and signed up for. However on my online account unit rate is 15.6975p per kWh and on my welcome pack that you have sent me on the 10th the unit rate is 14.95p/kWh. Thus I am confused. Can you please explain me the charges and confirm the correct unit rate per kWh. Also I expect it to be 13.503p as this is again the original offer that I have agreed to when making a switch.
