Bad Service

I have sent several emails and several whatsapp's with NO reply from them after reading it. I buy every month for the last couple of years from them for my house R1500-R2000. Last month (Unfortunately I have thrown my receipt away as no one keeps their receipts) I bought again for R1800 and 5kg of my roast beef and 4kg of my boerewors was a DISASTER and nobody gets back to me regarding this. I even used my roast beef for soup and potjiekos and it still as chewy as nothing you can explain. The boerewors skin is so hard you can't bite through it and the meat inside taste like flour......... i don't if you are willing to give me an explanation or just leave it like it is and loose a client that buy from you for years
