Horrible service

Very disappointing service I received at Roots Sky City, I bought double pack mince and when were eating the mince it had gizzards dirt in it, i threw it away and cooked the second pack thinking it will be different but it was still the same, I then went to the store to report it and the lady that spoke to me said I am the second person complaining about this and she will get the owner/manager to call me the next day but till today no one has called me, this is very disappointing service considering that roots is a trusted franchise, such customer service is a disgrace, I have reported to Cassilda at their head office hoping my complaint will be attended to
