False Promises and Let Down after you pay

Very poor experience and still ongoing. We found the info on SBCA online and we were contacted and assigned Deveshin. We had one phonecall and a few emails where we asked questions to make sure we are aligned. He promised us support, and seamless, and a touch base meeting with the Cloud Conversion team and also an alignment on a schedule so my 133mb little file can be loaded. So far we have no contact details, emails missed, all commitments not done and a missed deadline of ours even though he literally promised not to let us down. No direct contact details and returned emails after hours or sometimes not at all is what we got after making payment. Its just about the sales and commission and collapsing small businesses. Hopefully tomorrow he sorts it out and we only have 1 day of cost and damage due to his false promises that have taken us backwards. It was a mistake trusting his dales pitch. The sorrys about the inconvenience now mean nothing after he has done the damage. If he is unable and any better contact people at Sage can give me what I've paid for, please do
