ordered and paid for but no luck

We bought 2 king-size beds in January and the Senzo promised us it will be available before Easter Weekend with the delivery before 15 March (six weeks)... on 29 February I sent an email to Senzo to check if we are still okay for delivery and ask him to call me . On the 1st of March he reply on email with \the beds is approaching its 6th week of production and the Randburg order controller will give me a call to arrange delivery\" After a lot of call's and promises no luck. Today 23 March Senzo is telling me the tables is available in Durban, they can sent it to Randburg tomorrow and the they will them book it for delivery to me in Pretoria or I must collect from them.... After they charged me R1425 for delivery...WTH? "
