Damaged goods not yet replaced

Hello Peter<br> On 17 January 2014 I handed 4 damaged items in at Tupperware in Vereeniging Bashee Street for replacement.<br> On 25 March 2014, 25 June 2014, 5 March 2015 and 13 March 2015 I phoned them on *** with my receipt number to find out when I will receive my goods back. Every time I phone Lindiwe promised me that she will follow it up. Well today is 8 April and I still have not heard anything. I cannot believe that Tupperware who claims to have a lifetime guarantee on their goods can be so slack in replacing the items.<br> <br>
