WORST SERVICE AND REFUND PROCESS

i bought tummy belt from home mark i paid cash , the belts are not as advertised so i returned it the manager couldn't refund me cash as he didn't have any sales for that day , he asked me to return the next day which i did , still no cash refund , on the third day he decided to take down my cell number and if he got cash customer he would call to refund me . this transaction started 19 Jan til date 22nd Jan no call , no service , no refund this is in the Alberton Mall . i will never again buy anything from this store
