Williams Communication Services Limited

I went to Majestic Communication in Oshawa, Five Points Mall about one month ago to replace iPhone 4s battery. Paid cash $35 without the receipt, the associate told me that I have 14 days warranty on that battery. I brought it home and charged it per directions given by a girl who was working there but the phone was not working properly right away. The battery still last not long, had to charge my phone twice a day. So went back to the store and they change again the battery and the guy told me that he will gave me money back if it doesn’t work within 14 days. They said I have 14 days warranty on that new battery. So I give it a try, again no change and the battery still didn’t last long and again had to charge my phone twice a day. Almost month passed and nothing change, still have the same problem my phone didn’t get fixed like they promised. I called the store and a guy told me to come in so they will return my money. I went to the store they took the battery of from my phone and tried to give me my iPhone
