No product back-up

Has purchased an shower kit from a retailer and when I wanted to fit it I found that the wall channels supplied were incorrect I went to AGI and asked them if they have the correct profile in stock as described in the fitting instructions which they confirmed they do But they are not willing to sel me induvidual components and said that I should buy a new kit They will take my number and have a discussion with management when management is available to see if they will be willing to sell me the correct components in order for me to fit thier product In the meantime I guess I will just have to do without a shower untill such time is they get back to me if ever
