You are now ready to chat with Ashish.
Ashish: Thanks for contacting EA Help! My name is Ashish how may I help you?
you: i am experiencing diddiculties with the packages in mass effect 3
you: the multiplayer ones u buy to unlock new stuff
you: when the error comes up it tells me to contact customer support if the issue keeps on happening
you: i have literally lost a couple of hundred thousand in game credits due to this error
Ashish: You meant commendation pack, right?
you: not sure, in multiplayer you go to "store" to purchase the recruit veteran or spectre packs, they are what are giving me the problems
you: wasnt sure if i was to contact ea support or playstation support?
Ashish: I can understand your concern. Please don't worry, I will try my best to help you out.
Ashish: I would need some time to investigate this, please stay connected.
you: need to get it fixed as it makes playing multiplayer a nightmare
you: will usually allow me to buy a couple of packs and then it goes to the error, then i usually reset the ps3 and it will work again but most of the time it has taken most of my credits
Ashish: Okay
you: maybe 2 days ago i had around 150 thousand credits, went to buy a spectre pack for 60 thousand, came back with the error, reset ps3, i then had 3.6 thousand credits
Ashish: Okay.
Ashish: Please give me just a moment while I look into this further.
Ashish: Please stay connected I am working on your issue.
Ashish: I appreciate your patience and cooperation.
