At Wetherby Computers we operate a very simple "No Fix - No Fee" principle which we always explain to customers.
If the remedial work that we are to undertake is not successful then we will not charge you for our time and efforts.
We are confident after performing many thousands of repairs that we can very accurately gauge what repairs will be effective and which will not.
There are exceptions to this rule which, again, we always make clear to anyone we speak with.
If the work that you wish us to undertake can NOT be guaranteed by us then we will make this very clear before we do anything.
