Harassed by takealot

I am being harassed by take a lot now, I had a collection booked on the 25 of May, after I realized that on the collection date I won't be home I cancelled the collection and got another reference number for a drop off, parcel was dropped off, last week I get an sms for a scheduled collection, I call the call centre and explain to them that package has been dropped off already then the person I spoke to said the collection order has been cancelled and error fixed tuesday the 3rd of June I get a call from a driver who at my gate to collect I tell him the package has been dropped off a week ago, then he says ok he will tell the centre Wednesday I get another call from a driver who's here to collect

Thursday again I got woken up by a knock on my gate a driver is here to collect again, this is now harassment

Please fix the error
