Willard and Midas

I bought a 669 willard battery on 1/08/2018 with a 25 month warranty at Sonnys midas in Brakpan. I have had to push start or jump my bakkie virtually everyday for the last month when i visited midas they tested the battery with a electronic device which says the battery is ok but they did not do a load test. So i took my vehicle to Kennys auto electrical he did a load test after 15 seconds my car will not start. He checked the charging system and found it to be ok. i called the willard rep and he just said my car is not charging enough.this is very poor service from supposedly reputable companies.
