Takealot but deliver a little

On the whole Takelot is great.... BUT when they get it wrong they get it wrong. I order 3 by Simparca in October They delivered 1 I returned it and wanted my other 2 They delivered 1 I returned it and wanted my other 2 They delivered 1 I am now trying to get them to refund my initial purchase... In the mean time I cannot treat my dogs against ticks... Will they pay my possible vets bills?
