Simple request taking 3 months to execute

We recently moved into our new home and the previous owner left a drum from Pretoria Domdieste on the property. I made contact with them in November 2017 and asked them to please come and collect the drum, and that we are not interested to take out a contract with them. Its been 3 months and several emails - the drum has still not been collected. Please think twice before you make use of this company because the service is terrible.
