I have read a lot of posts on here about difficulties, switching customers to wfp. I honestly find this hard to belive. I have only just started out for myself this month. Previously worked Trad for another windi. So beginning of January I started subcontracting 7 village rounds from him. I have swaped them all over to wfp no problems at all. Just told them it's laboratory grade pure water, any problems pls call. No calls no complaints . Better yet found out today word is going ahead of me and customers are keen to see this new fangled way.
