Not charged pro-rata on the wifi device

Hi Sir / Madam<br> <br> I want my money back for the pro rata on the device not being charged. This is not what I was told by your marketing vendor Cell Direct.<br> After all the issue I had when taking the contract with Cell Direct , Now I get this .... Please I want my money back. I knew something was wrong with the bill when I saw the price.<br> <br> Called your customer center yesterday, and they said it is the activation fee and that's why , but the activation fee will be credited back to me , but when checked the post and the breakdown of the costs . The activation fee I see the credit so that blows her assumptions out of the way, but I also see no pro rata was taken into account for device for the March month , which resulted in a higher bill<br> <br> I need someone to call me and sort this out quickly. <br> <br> Thanks and Regards<br>
