Not enough info. When the compressor'seems to be working' what do the high and low side pressure readings do? that is only a small part of the diagnostics needed , but would be very helpful info.---You stated r-134 added twice EVAC & RECHARGE each time? or simply adding more to the system the second time? Overcharging can cause no-cool conditions also.
