Poor Service from S & H Electronic Services

Extreme delay in delivering items purchased. Refusal to send to Post Net at my request as I am single and have no one at home to receive the parcel Despite my informing them of my cell phone number, originally typing it as +27 with the following 9 numbers and finding that on their form the last two digits were omitted due to lack of space, I then submitted the number starting with a zero. They said that they could not contact me due to a so called incorrect number, but they did not check their emails from me to see the advice of the number starting without the +27 and stating it to begin with a zero. They now demand extra payment for delivery despite the fact that delivery / courier fee charges were paid when making the purchase. I have found them to be extremely obstructive and not user friendly. The old adage is that the customer is the person to be considered first. Not the case with S & H Electronic Services
