Deductions & credits

My federal refund was $2878 when i filed through turbo tax they also said they were charging me $78 for the fees which i agreed to however turbo tax went through a third party TPG PRODUCTS SBTPG LLC and they shorted me over half my return  i only received $1,355.74. i sent an email to the tpg email they sent my "return notification" through they responded back with your request is being reviewed or whatever but that was 2 weeks ago and i haven't heard or seen any further action i have bills to pay i need this money just to survive in this world where the cost of living is constantly going up i need this resolved or i will be taking action this is absolutely ridiculous turbo tax ive seen people complain that they were shorted more then half there refund when there refund was 13000 im seeing people complain all over why haven't you cracked down on this situation your a professional company but allowing things like this to happen is not very professional.
