No delivery for over 3 months!

I ordered your smart home package and was told the waiting period was 7-14 days, after 14 days i called to enquire where my items were and was given a tracking number and telephone number of the courier - when i called them they informed me that this had already been delivered ---- to wrong address and wrong person! I informed Telkom and they said they would sort it out. After around another week i received a call to say you were trying to deliver to another address -- not mine again!! Eventually my parcel arrived but when i opened it half of the items that were supposed to be delivered were not in the box - again i phoned Telkom - again they said they would sort it out! After around 2 dozen calls i received another tracking number - again incorrect address and contact on package - last week i received my 4th tracking number and again you delivered to the incorrect address!! Shocking service and absolutely no response back from any of the managers i have been dealing with! WHERE ARE MY ITEMS!! I can not believe this terrible service still sitting without half my items but i am being billed!
