"I have been very ill for the past week and ... my doctor has said I cannot return to work for another week.
"This put a huge strain on my finances, I had no idea how I was going to work it out."
Linda's budget was already tight as she had her grandchildren staying with her. She was also trying to fit her family's groceries into a beer fridge because her regular fridge had broken down and needed fixing.
"They wouldn't have known any of that," she said.
"This happened at such a time I really needed it."
Linda said the gift from "these two angels" took "a huge burden" off her shoulders.
"I wish I could see them in person or communicate with them in some way so I could tell them myself.
"I will definitely get a bottle of wine for myself from them, and enjoy Mother's Day to the fullest."
Linda said she would also be "praying for many blessings for this loving couple".
