Align sounds like a problem but I have seen poor connections, hidden diplexer (but this normally kills most of the ka signal on 99 and 103), old au9..etc. I will almost agree with most here and say the tech doing the alignment was out for a paycheck and did not properly solve you problem. If he did align the dish properly but it does not have a solid mounting ( adjustable stay legs, soft/semirotten wood mounting surface) the dish will sag or move out of alignment. I would have another tech out and donot accept anything below 93 on 103c, 96 on 101, and the rest should be there.
