LOVIES NAPPIES POOR QUALITY

Good day I have purchase two packs of no.3 from Shoprite phoenix plaza , I have have notice that some of the diapers only have one strap and the others dont stick at all, please can someone advise me on what to do, cause this is not called for , at the end of the day we are spending our money trusting the name and getting poor results for these nappies.
