Over two months later and still waiting for a business contract or any communication

I have been attempting to acquire a business contract since early March. It is now the 5th of May and no response from the customer service rep. I have sent multiple emails but no response at all. I was give the excuse that there was no stock on the 10th of April and stock would be arriving on the 20th of April. I then followed via email on the 22nd and yet still no response. If this is how a prospective client is treated, I'd hate to think how they treat retained clients. Should I not have this resolved today, I will simply take my business to another Network Provider.
