reload software for blackberrys *

I fix blackberry smartphones with reload software problems eg.reload software 552 or reload software 507 why take it to the shop and pay as much as 30 pound and wait weeks? i can do it within 1 day and only charge 10 pound so if you need your phone fixing email me please do not call or text becuase i have just fixed my phone and have not activated my services yet also forgot to mention if for some reason i cannot fix your phone you will get a full refund
