Fix or redo eCommerce pages on my web site

I have a website [login to view URL] and I got [login to view URL] to build me eCommerce pages under a new tab at top- see this link... [login to view URL] As you can see this is a test version of my original site including the new eCommerce Pages. it is not finished and I am convinced that because they refuse to contact me that they dont want to finish this project and now I don't know what to do!! It has been over 6 weeks weeks and they promised me this done in 2 weeks! Can someone either redo this job with the same info or copy it onto their web space and continue it? I would like this completed ASAP at a good price as I have already spent $100 on it and I had more to pay them when done but they dont seem to care. Basically it is done but they didnt know how to make the AddThis buttons work independantly on each item in the shop and they didnt know how to add Paypal as an option in the cart, nor did they know how to embed a website within the Heading entitled 'Aromatherapy'. ( I am an affiliate for DoTerra Essential Oils and the easiest way to have people buy on that site is to embed that site inside mine under the Aromatherapy Heading. Believe me I have looked at a lot of options). All the other Heading are ok excpet I accidently saved the top heading blank so its glitching and I notice the headings only allow a certain amount of letters so they are truncated. This eCommerce section of my site needs improving. Please help. I would prefer to access the back end of this eCommerce Page from the main site backend which is [login to view URL] I use my own mobile EFTPOS machine to manually input the credit card details so the site sends me an email capturing their card and order details. Give me a good price people. I would prefer people with good English and the ability to Skype with me or on the phone so I can work this project with you fast.
