Help Please?

I am writing to you on this platform in our desperation for kind assistance. I unfortunately lost my husband late last year... during the processing of things, I made the impulsive decision of changing the cell number that he used, this was done by a LOVELY lady at Vodacom in Woodmead however I really really regret my decision and would really like to have the number re-instated for my son and daughter one day... I am asking if you could please please assist in possibly reinstating that number to my contract... I have been a loyal client for years and years and would really appreciate this if possible?
