Pathetic Customer Service - Late Delivery- no comm

On Tues 2 June 2015 we, (Transformers Panel Shop Cape Town), ordered a part for a vehicle that was involved in an accident. There were no parts in Cape Town and we were told that it would have to come from JHB and that we would need to pay a 50% deposit to secure and speed up delivery which I paid. We were further promised that the part would be in Cape Town on Thurs 4 June. On Thurs 4th we were called only to be told that the part was not here and that in fact ALL the parts were damaged and that they could not send us one. I instructed them to send the best of the lot as we needed to finish the job. We were promised discount as we would only receive the part Mon/Tues the following week. We were only called today Wed 10th and told that the part had arrived in Cape Town but that they would not deliver until the balance was paid. After everything that had happened I insisted on seeing the part prior to final payment which I would do immediately upon delivery and inspection. They would not refused until funds were actually reflecting in their account or unless paid in cash, I was forced to pay the full amount prior to delivery with no discount. Ridiculous!
