I am trying to have a defective Momo7 replaced by McBub. Order #1075772. Took very many emails and calls to their office to explain to them that the unit was defective. Very frustrating. They have no clue about these items, they confuse the models, the software installed, etc. Absolutely unprofessional. Then we were given instructions how to send the unit back to them, but told NOT to send by courier (DHL, Fedex etc). Hence, we send by regular mail (Canada Post) and copied to them shipping information together with images of the parts, forms completed etc, But now they are complaining that they have no tracking number and will not forward a new unit until they receive the defective one. This will take months! By that time, the unit is not only outdated, but also available at a lower price. I rather have my money back onto my Paypal account. This is not the first tablet I bought from them, but will be the last.
