Poor service, Failed Delivery

Hi, as mentioned above it is Build-It Bochum, Senwabarwana, after my complaint i only received 1 call from someone I'm guessing is the manager and i have been promised delivery since and to date i have been fighting telephonically with this people, even Solly the sales person kept promising delivery and still nothing, i have called this morning and was told delivery is being done in the morning nd till now there is nothing, now they are not even answering my calls... this is so disgusting after spending so much money, i paid cash for my roof tiles over a month ago and delivery is not happening, you either deliver now or refund me my money, what a waste... i would never recommend anyone to you guys or even use you ever again
